Variable | Range of Values Found | Values selected for project | Speed of Bullet | 1055-3054 Feet Per Second** | 3054 feet per second | Power of locomotive | 3000-6000horse power | 6000 horse power | Height of a very tall building | 859-2716ft | 2716 feet |
Chose the highest value for each area because I figured it would be best to compare the top amounts.
Speed of bullet – 4122.9 watts
Power of locomotive – 4474200 watts
Height of building – 2716 feet
**Bullet speed varies greatly depending on size/shape/weight of bullet and distance from muzzle (wind resistance and gravity).
Volume for water = ((3.1417 * Radius^2) *Depth) * 7.47 = gallons *8.35lb = weight
97,001,173.49175lb’s
E=10^(1.5(9)+4.8) = 10^(18.3) = 1.995262315x10^18jouls
1515.428229m/second
.941643154 miles per hour
5500 miles
My bullet goes 930 meters per second.
The power is astronomically higher then that of the locomotive.
The height of the building I chose is 827 meters which is a lot larger then 10 meters however when you compare it to the 15 mile dept while in the ocean iits much smaller.

...Math History Essay Math is a subject I enjoy doing. Every day when I come home from school, it is the very first thing I do. Math is by far my favorite subject. It is more exciting than memorizing facts or writing an essay. Math involves thinking and solving, and I like to think through and solve problems. Even though math is not my strongest suit, I still enjoy doing anything related to it. Interest in taking Pre-Cal began during my freshman year. Two years ago, I took Geometry and fell in love with it. I enjoyed everything from proofs to finding the area of a shape. I remember people complaining how difficult Geometry was and thinking the exact opposite. By the end of freshman year, I was sad that Geometry was coming to an end. However, I was informed that Pre-Cal is similar to Geometry and is offered my junior year. Ever since then, I could not wait for Algebra 2 to be over. I also decided to take this class because it will build the foundation needed for Calculus the following year. To be successful in Pre-Cal this year, I will try my best to spare time to review notes I took the day before. I will also spend time with a study group so I can get advice by my peers. Whenever I have unanswered questions and cannot contact a teacher, I can rely on my friends who can explain and guide me along the right answer. As a teacher, you can walk around the class when there is extra time to do homework to easily answer questions that I may have regarding the assignment.......

...APPEARED IN BULLETIN OF THE AMERICAN MATHEMATICAL SOCIETY Volume 30, Number 2, April 1994, Pages 161-177 ON PROOF AND PROGRESS IN MATHEMATICS WILLIAM P. THURSTON This essay on the nature of proof and progress in mathematics was stimulated by the article of Jaﬀe and Quinn, “Theoretical Mathematics: Toward a cultural synthesis of mathematics and theoretical physics”. Their article raises interesting issues that mathematicians should pay more attention to, but it also perpetuates some widely held beliefs and attitudes that need to be questioned and examined. The article had one paragraph portraying some of my work in a way that diverges from my experience, and it also diverges from the observations of people in the ﬁeld whom I’ve discussed it with as a reality check. After some reﬂection, it seemed to me that what Jaﬀe and Quinn wrote was an example of the phenomenon that people see what they are tuned to see. Their portrayal of my work resulted from projecting the sociology of mathematics onto a one-dimensional scale (speculation versus rigor) that ignores many basic phenomena. Responses to the Jaﬀe-Quinn article have been invited from a number of mathematicians, and I expect it to receive plenty of speciﬁc analysis and criticism from others. Therefore, I will concentrate in this essay on the positive rather than on the contranegative. I will describe my view of the process of mathematics, referring only occasionally to Jaﬀe and Quinn by way of comparison. In attempting......

Math Essay

...The history of Geometry started in Ancient Egypt around 3000 B.C.E. Egyptians used an early stage of geometry when surveying the land, construction of pyramids, and astronomy. And around 2900 B.C.E. they began using their knowledge to construct pyramids with four triangular faces and a square base. It was created because it was a collection of empirically discovered principles concerning lengths, angles, areas, and volumes, which were developed to meet some practical need in surveying, construction, astronomy, and various crafts. It was used in Babylonia and in the Indus Valley by the Egyptians, Babylonians, and the people of the Indus Valley but the creators were Pythagoras, Euclid, Archimedes, and Thales. Pythagoras was the first pure mathematician although we know little about his mathematical achievements. He was also, a greek philosopher and created a movement called Pythagoreanism. Euclid is sometimes called Euclid of Alexandria. He is also called the “Father of Geometry” and his elements were one of the most influential works in the history of mathematics, which served as a textbook used for teaching mathematics (especially Geometry) from when it was published till the late 19th century to early 20th century. In the Elements he included the principles of what is now called Euclidean Geometry. Euclidean Geometry is a mathematical system and consists of in a small set of appealing postulates that are accepted as true. In fact, Euclid was able to come up with a......

Animal Math Vs Gut Math Essay

...The central idea the of two texts is frequently shown throughout a brain research article. In text A, “Gut Math” tells the difference between “formal math” and “gut math”, while text B, “Animal Arithmetic” focus on providing examples of animals using “‘gut math.” Both of texts tried to proves humans and animal are born to do math in many different ways. As kids grow up they learn what math is and slowly start to dive into basic math eventually evolve into algebra, calculus, and geometry. However, text A “Gut Math” states in paragraph 3,” What does comes naturally though is the ability to approximate.” Meaning that the ability to approximate is part of the brain since birth. Therefore, there are two separate mathematics areas of the brains, one of which is “formal math” that’s what taught in school, and “gut math” an inborn...

...At times, thoughts of walking away crossed my mind due to the short amount of time. It was as if I was fighting an inner war with myself. However, once I started writing the essays it became something easy and natural for me. I was able to finish both essays on time and I felt as I won to my other side who said that I was not capable. After a few weeks, the test results were posted and to my surprised I passed the CBEST and got a high score on the writing section. I was very happy and realized that I needed to start believing in myself and not to let negativity stop me from reaching my goals. Now I enjoy writing and mostly I’m not afraid to...

Fixed and Growth Mind-Set

...Fixed and Growth Mind Sets As students growing up, we tend to get fixated on classes we like and dislike. The essay “The Perils and Promises of Praise,” by the author Carol S. Dweck explains that the mind has two different mind-sets. Those are fixed mind-set and growth mind-set, which explains the different ways we think about our intellectual abilities and how well we will do in our classes. A person with a growth mind-set believes that they are able to expand their intellectual ability by putting in effort (Dweck 7). People with this mind-set are willing to work hard and struggle with difficult tasks because in the end they will have completed that task and be successful (Dweck 12). A person with a fixed mind-set believes that they only have a certain amount of intellect, and that it cannot change (Dweck 6). When a person with the fixed mind-set is confronted with a difficult task, they usually give up or resort to cheating to pass (Dweck 10). Educators commonly believe that praising students' intelligence builds their confidence and motivation to learn (Dweck 9). After reviewing the differences between fixed mind-set and growth mind-set, I figured that reading and writing is the subject where I have a fixed mind-set, math class is the subject where I have a growth mind-set. Some people assume that intellectual ability is a fixed trait, that either they are smart or not so smart. When students become aware of the plasticity of the brain and being able to shape their......

Ghosts of Educations Past

...7/29/12 UNIV103, Unit 2 IP Ghosts of Educations past Coming back to school after so long was daunting, but I could not have been happier for making the choice I have. In my first course I have been asked to complete an exercise called the MFL Path Builder. As I worked on this request I found I remembered much more than I thought I would, and forgotten just as much. There are three basic topics that include Writing, Reading, and Math. In high school I was very good at math, but I found I am just a little lacking in memory of all the rules math requires. Whereas I never excelled at English in high school; but was pleasantly surprised when I mastered 3 out of 4 modules in Reading. Oddly enough though in Writing, I completely tanked. After finding out just how much I have remembered and forgotten after so long, I find I am very anxious to get started on all the topic’s contained in each module. I started my IP by setting aside time to myself each night to focus on completing the MFL Path Builders. After completing the path builders for each topic I believe it did just what it should have done. It showed me just what I need to re-learn and catch up on. I feel that this tool was made to help new students that have been out of school for a long time; succeed in their education, and give us the same chances as those students who have just gotten out of other educational programs. I was pleasantly surprised buy the tool this program has given me and my chances......

Two Esays, What Are the Differences and What Are the Simlarities?

...Compare and Contrast Essay 5/12/2014 Ashford University English 121-AXC1415E Instructor: Jamie Cooper Student: Katherin Wheat When it comes to writing the compare and contrast essay style, it is one of the more difficult ones to achieve. The differences between these two essays “How to say nothing in 500 words” by: Paul McHenry Roberts and “caged bird” by: Maya Angelou is easy to pick out. As far as the similarities goes that proved to a little harder to give a lot of examples. In the following paragraphs there will be plenty of examples of compare and contrast, give summaries, a couple of quotes and a paraphrase will be included in this essay. While how to say nothing in 500 words and Caged Bird are both well-written essays, caged Bird was more visual than How to say nothing in 500 words because the author painted a more detailed picture which kept the reader’s attention, the attended audience was more overly open to more people than that of how to say nothing in 500 words essay, and the author of caged bird had a bigger and deeper impact on the readers then the author of how to say nothing in 500 words did. Caged Bird was more visual than How to say nothing in 500 words because the author painted a more detailed picture which kept the reader’s attention. Maya Angelou’s descriptive essay “Caged bird” tells a story of a caged bird and a free bird. The caged bird signifies a person with the skin color darker than that of a peach colored crayon, held down by the......
