... In this experiment as you can see from the table its similar all the way around. When you shoot from the spring gun and you pull back the sling shot, when you pull it back multiple times at the same distance each time you will pretty much get the same angle’s. Also when you calculate V1 and V your answers will be very similar. Analysis 1) Describe a different method for measuring (Y2 - Y1) By making a right triangle out of the strings attacked to the block, then using cosine to find the missing length and, then subtract from the original length is another method of finding (Y2 - Y1). 2) Describe a different method for finding V1 The method that we used in the Dart gun Lab to find the Velocity , where we used the displacement and angles to find the velocity of the objects is one method. Another would be the using the equation (m1 x V1)+0=(m1+m2)(Vf) And Vf=V1. Human Error There are many different ways of human error for the experiment. One would be not inserting the steel ball completely inside the spring gun and it falling out or shooting in a different direction. Another would be if you didn’t have the stationary pendulum secure to the strings holding it up and when you shot the pendulum fell and the steel ball went flying. Also if the apparatus is to short, long or not attached completely. If the steel ball the stuck inside of the spring gun.

...properly. When this occurs, you may have to pull the slide back to manually remove the jammed bullet. It's frustrating to say the least when you spend more time adjusting the slide and removing jammed bullets than you do actually shooting. Many people automatically assume that semi-automatic pistol jams such as this are caused by a mechanical error, at which point they take their pistol to a local gunsmith. But a more plausible cause is a phenomenon known as “limp wristing.” What is Limp Wristing?...

...Australian Fruit Juice industry consists of 56 wide ranges of beverages including flavoured water, iced tea, and fruit drink and fruit juice, with 4 major companies representing 71.5% share. The industry had an annual growth of 1.1% in 2008-13, businesses profited over $106.2m creating the industry revenue of $2.0 billion. The major findings indicate the importance of correct advertising and labelling of fruit juice this ensures that no legal matters are taken against the business, how black-label brands hold a 10% share of the market holding a threat to other business with the ability to charge lower prices and committing more shelf space to their own fruit juices and how important it is for business to follow customer trends as they hold the purchasing power. The report also compares and contrasts Boost Juice Bars and Spring Valley Juice marketing strategies, recommending that Boost Juice Bars continue on with their strong marketing mix and Spring Valley focus on their customer trends and target market. The report also recommends the industry swap to BPA free plastic bottles to better enhance their brand and health and safety of their consumers. Table of Contents 1.

...rather rapidly at a perpendicular angle of the green arrow. The velocity or green arrow is always pointing in the direction I am moving and since I am going a constant speed it stays the same length. The blue arrow is showing the acceleration due to the rotation and it fluctuates rapidly due to me being unable to create a perfect speed and circle around a focal point. 4) Now move the ball at a slow constant speed across the screen. What do you notice now about the vectors? Explain why this happens. When I move them in the same direction they are even/on top of each other. This happens because the velocity or direction and speed are constant making the acceleration constant. 5) What happens to the vectors when you jerk the ball rapidly back and forth across the screen? Explain why this happens. The blue arrow goes with the green the shoots in the opposite direction shortly after. This happens because of the ball decelerating rapidly before traveling in the other direction and repeating the process 6) Now click on ‘Circular’ on the bottom. Describe the motion of the ball and the behavior of the two vectors. Is there a force on the ball? How can you tell? Be detailed in your explanations. Since the speed is now constant, the velocity...

...Looking back, I remember running through the long lush grass pretending we were at battle and trying to take cover. I would always find myself behind the old oak tree in our back yard. This was my favorite spot. The thick trunk, like a bodyguard, protected me from the imaginary bullets that flew towards my body. I would lean against the hard bark and for some reason it was comforting to have something sturdy to lean on. It was dark brown, and every now and then a spider would nestle between the pieces of bark. Sometimes I would touch the tree to peek around the corner and my fingers would be sticky. I could never quite figure out why that was, but, nevertheless, I had the hardest time getting it off, a constant reminder of my tree. When my little brother, miguel and I weren't at "battle," I would lay beneath my oak tree and daydream. As I looked up I could see millions of branches protecting me from everything above. At the end of each branch were hundreds of more leaves that would gently catch the morning dew, and carefully allowed it to make its way to the grass. It was like thousands of stars in the sky as the sun caught the drops and allowed them to sparkle so brightly. This was my heaven, and as I lay there, I could feel the plush grass, like a snuggly old blanket, holding my body gently against the ground. Sometimes the grasshoppers would appear from around a blade of grass as if they were asking for approval to jump on my blanket. Every so often a leaf would jump...

...Joints of Staff and decorated as a war hero in the Persian Gulf War, Desert Storm and is relaxing in his place of residence in Palm Beach, Florida. All of the sudden while watching TV, a big loud thunderous crash is heard and Powell runs to the back yard to see what is going on. As he reaches the back yard, a funny looking vessel is sitting in his rose garden. As he goes to open the hatch, he is sucked in and bam, in the speed of light he is transformed back in time. After re-landing in the middle of a road, Powell opens the door to complete darkness and woods. The next thing that Powell sees is two men on horseback saying the British are coming, the British are coming. He stops one rider and Powell asks who are you and what year is it? The man replied, “ I am Sir Paul Revere and it is in the year of the our Lord 1777. Could this be, could he have stepped back into time, why him, why now? Colin starts walking and finally after two miles of bare and naked road, Powell stubbles upon a farm house and walked up to the door and knocks. “Who is thou at thyest door?” shouted from the house. Colin replies, “I am General Powell from the United States Amry.” The patriot upons the door and is startled by the appearance of the man. Holding a latern and dressed in Revolutionary style uniform, the guy eventually allows Powell to enter into his home. He asks Powell who he is and where he came from. Come and sit, says the man. He then begins to pry into Powell existence and intentions...

...the subject. Policies on recycling have a wide effect on how people decide to recycle. Viscusi, W., Kip; Huber, Joel; and Bell have collected information from many sources and analyzed this data to show the effects of recycling throughout various communities in the country. The information can be used for the project because it addresses the recycling aspects of a product and how consumerism impacts that decision. The article is written from information taken from a wide variety of sources that can each be verified because they are noted in the article. There has been a mathematical system made in the article to back up claims that are made and can be analyzed by the reader. Lambert, Jennifer R.

...The Mistake of a Party A Normal School Day It was a mild, sunny Thursday in the middle of March at Surewood High School where the seniors were throwing together a Spring Break Senior Bash. The bell rang for tenth period to end. *RING Sierra was standing at her locker grabbing her homework out for that night when suddenly she dropped her History book. *THUD She knelt down to grab it when Brandon came over and bent down to grab it too. Simultaneously, they both knocked heads. *THWACK “OWW!” both of them shouted as they stood up. Brandon was holding the History book. “Uh, I think this is yours,” said Brandon as he gave Sierra the book. “Yeah thanks,” said Sierra as she smiled back. “Oh, by the way, how are you? We haven’t really had time to talk since we were freshman.” said Brandon. “I’m fine thanks, and while I was known for being quiet and shy, you became Mr. Popularity,” said Sierra remembering the big crush she had on him back then. “Ha! I know - hey, how would you like to come to a party I’m throwing tonight at my house? It would mean a lot to me if you would come,” said Brandon. Other students, especially seniors, are now swarming the hall listening in on their conversation, including Emily. A little background on Emily is that she is the most popular girl in school and she always gets her way. But most important, she has always wanted Brandon to be her boyfriend, but that still has NOT happened, and she gets jealous of Brandon talking to Sierra. Emily walks...

...symbolic manner, the daffodil represents the life that Trethewey and her mother has had to endure. Although the daffodil is only mentioned in one poem, many poems throughout Native Guard illustrate how the life of the daffodil is directly related and compared to Natasha Trethewey and her mother. The order in which the poems are mentioned is also significant; they demonstrate the progression stages of the two lives mentioned and the devastation that is brought when a life is lost. At the beginning of the book in the poem “Genus Narcissus” the daffodil is being compared to Trethewey as a child, because they are both in the beginning stages of life. Comparable to the flower Trethewey would be considered a new bloom sprouting in the early spring. “The road I walked home from school was dense with trees and shadows, creek-side, and lit by yellow daffodils, early blossom” (1-3).They are both innocent beings beginning life and Natasha is awaiting the chance to endure the happiness that life has to bring. Both Natasha and the flowers are considered gifts to her mother, therefore she sees herself as being one with the flower, “Childish vanity. I must have seen in them some measure of myself- the slender stems, each blossom a head lifted up” (13-15). Being a young child Natasha did not know that the flowers given to her mother as a small gift would one day represent the bruises and sudden death her mother would quickly endure. The transition has now begun, the daffodils are starting...

...His Only With the gentle cracklings of the dusty record player jumping back with each rotation. With a room that had a scent of musk and stale perfume. In the cold white hospital room, the two lovers held hands for what may be the last time. June laid in the pearl white bed with Sydney on the green stool holding her hand waiting for her to wake one last time. The sweet young nurse entered the room in her bright pink scrubs, with a tear in her eye to set the record back to the beginning, Sydney started to sing along with his rusty voice that stood out amongst the beeping machines and the defining silent halls. Softly if only for his beautiful wife he sung. His face carried a gentle smile that helped hide his mournful eyes. As June’s eyes opened...

...new coat next winter" (P.63. L.10).This is what she is thinking about doing in the future if she would win the scholarship the next years. The dreams of Nancy also show that she is a goodhearted person, especially when it comes to people of her own race. The way that her dreams is pointing out her goodness, is the dream about America being a country without race discrimination. Nancy Lee and Miss O'Shay, who is the vice principal, have some things in common. They are both from another country, and both the Irish and the black people who immigrated to America have been exposed to discrimination "years ago we were called the dirty Irish" (P.67. L.1) and "we were invited to go back where we came from." (P.67 L.2). Another thing that Nancy and Miss O'Shay have in common is the believing in the American dream, the right to life, liberty and pursuit of happiness. They both want to live the American dream, live in a country with justice, equality, liberty and no discrimination. The way we can...

...friends and ICE MAN. Then I am going to focus on the theme and message in the text. Victor is from Arizona, he came to Palm Springs with his boss, to work. Victor is holding one hand in the air, when he is riding bulls, he is very cool and do not bother if the bull is angry, he just walk away with his back to the danger. The behavior he have, when he rides bulls, also shows in his behavior in other part of his life. Example, when he is in the bar celebrating his first place with his friends, and the ICE MAN is rude to them, he shows no fear of authority, and starts to mock. “My Mimbreño Apache name is Deer With Horns Running Through the Woods Being Chased by a White Dude Wearing a Cowboy Hat.” (ll. 105-106) , He know that will infuriate the ICE MAN. Even if he know, there are deputies in there and they are outnumbered. Victor is generous, you can see that, because he bye alcohol for his friends. Victor decides to provoke ICE MAN, because he is so full his own title. In addition, he said, “cause you people”, like they are any different form white. Victor seems to be very proud of being Indian, and stands up for his people and race. He is passionate about his job as a bull rider; you get a sense of that when he talks about it with his two friends. The two friends is also Mojave Indian boys, Nachee and Billy Cosa, they also came along to Palm Springs from Arizona when Victors boss moved his business. The two friends seem to be more tempered than Victor is, or that is the impression...

...cleats or pilings – so far, so good.We often see boats tied up with only two lines – one at the bow and another at the stern – with each line running at about a 90-degree angle from the boat to the dock. These two lines will secure the boat to the dock, but the boat may still drift slightly frontwards or backwards (fore and aft), potentially allowing the craft to bump into other boats, especially at a crowded pier.The correct method of making your vessel fast to the dock or slip is quick and easy, usually involving four mooring lines: a bow line and stern line to secure the ends of your boat to the dock; and two spring lines to limit the fore and aft movement of your craft.Bow and stern lines’ locations are self-explanatory; the bow line is at the front and the stern line is at the back of the boat. Spring lines hold the boat amidships (the middle), by running one spring line from a dock cleat...
