Data

Mass of Pendulum Assembly (M) : 81g
Protractor & Ball : 20.03 Protractor - 12.5 Mass of Bullet (m) : 7.53g



Results

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.

Ibis and Nibin

...IBIS The Integrated Ballistics Identification System (IBIS) which is an organ of National Integrated Ballistic Information Network (NIBIN) is used to capture and store evidence images in the NIBIN database. The IBIS refers to a computerized automated system linking firearms correlated evidence like cartridge cases, bullets and firearms to all forensic firearms. IBIS system was premeditated to recognize cartridge cases and bullets emerging from semi-automatic firearms whereby the National Integrated Ballistic Information Network (NIBIN) program is used to image and compare crime firearms verification. NIBIN NIBIN Program is used to automate ballistics evaluations and provides timely reliable investigative leads. By use of NIBIN, firearms inspectors enter cartridge casing proof into the IBIS and images are linked respect to the database. Evidence can be identified by law enforcers from the neighboring ones, jurisdiction and others across the country to share information and cooperating easily making all of us more effective in closing cases. The history of NIBIN It was established in 1999 by the ATF as a kick off of administration of the National Integrated Ballistic Information Network. It was in this program that ATF administers automated ballistic imaging technology for NIBIN partners: state, forensic science, federal, attorney agencies state and local law enforcement in the United States that have entered into a formal agreement with ATF to enter ballistic information into NIBIN...

Criminal Justice Reflective Paper

...since my junior year in high school I have been very interested in what crime scene investigators do. Inspired by the forensics class I took I learned that although their job takes a lot of patience and thinking, it would seem like the perfect job for me. Not knowing everything about this area, entering college allowed me to broaden my horizons. My major was Forensic Science but is now and remains Criminal Justice as I decided to branch out with a minor in Computer Forensics. Continuing to get more familiar with my minor I learned that within forensics there are technicians that work specifically with guns. This area is called ballistics; the scientific study of the characteristics of projectiles, such as bullets or missiles, and the way they move in flight. (Dictionary.com, 2012) Needless to say I had absolutely no idea of the specifics of a Forensic Ballistics Expert. After doing some research I have found significant information such as the qualifications, their salary, examples of the progression within the system and etc. The basic qualifications would be outstanding observation and...

Mathematics and Forensics

...such way is the science of forensics. Without math, forensics could not exist. As population growth increases at an alarming rate, people have to find ways of holding people accountable for unlawful behavior. Forensic science has allowed civilization to evolve and become less barbaric and move towards factual based evidence when solving crimes against nature. Forensic science measures facts involving a crime and figure out the truth behind those measurements. Whether it is the skid marks from a vehicle collision or blood splatter analysis; mathematics is the reason why this can be done. Forensics have paved the way to a better justice system providing factual based evidence based upon math laws that are accepted as truth. The study of ballistics and the trajectory of bullets is a crucial element in crime solving strategy. In the United States, it is everyone’s privilege to own a gun lawfully. If the majority of the people had guns, it would be important to have a way of holding citizens accountable. This is done with mathematics....

Ballistic Fingerprinting

...This assignment will explore the pros and cons of Ballistics Fingerprinting. My paper will be based on two published articles. The first is by Lorraine Woellert, whose article which states how ballistics fingerprinting can be extremely beneficial to a criminal investigation. Then there is Paul Magnusson’s article that states how ballistics fingerprinting is a waste of time and cost ineffective (both articles were published in BusinessWeek Online). Just like when a human hand touches a surface, it leaves a fingerprint distinctive to that person. When a weapon is fired, the marks and grooves left on the bullet when it leaves the barrel are distinctive to that particular weapon. Ballistics fingerprinting was crucial in the DC Sniper case of Oct 2002. The case came to an end when John Allen Muhammad and Lee Boyd Malvo were found sleeping in their car. Ballistics test done on the weapon found in the car, a Bushmaster .223 Caliber rifle later linked the weapon to 11 of the 14 shootings. I like this article because it states that this technology can help in solving a major crime. Because of the success of this, a national ballistics database should be established. On the other side of that coin, the next article explores the disadvantages of ballistics fingerprinting. A national database would be costly and unworkable. And it would be a distraction to police in their efforts of fighting violent crimes. At the time of this article’s publication, a major supporter of this program...

...3/12/14 A Defense of Hedonism Many objections have been made against the theory of axiological hedonism. I will not attempt to respond to all of them, but instead focus on one of the stronger arguments, which deals with life trajectories. I will begin by briefly presenting the theory of axiological hedonism and then present the objection regarding life trajectories to the best of my ability. Finally for the majority of my essay, I will argue for why this objection is unsound and does not prove that hedonism is false. Axiological hedonism is the philosophical theory that is based on the idea that the only thing in this world that is intrinsically good for its own sake is happiness. This is different from the theory of psychological hedonism, which says that the only thing humans are physically able to desire for its own sake is happiness. First developed by Epicurus and later revised by John Stuart Mill along with many others, the theory of axiological hedonism uses a distinction between what philosophers call instrumental goods and things that are intrinsically valuable to illustrate its claim. Instrumental goods are any things in the world that are valuable because of the good things they bring about. Things that are intrinsically valuable on the other hand, are things that are inherently good for their own sake. Axiological hedonism claims that happiness is the only thing that is intrinsically valuable. The argument for axiological hedonisms is roughly as follows: ...

Bloodstain Pattern Analysis

...14 December 2014 Blood and Guns The world of Forensic Scientist is an amazing and fascinating place. There are so many aspects that go into forensic science but in this paper we are only covering bloodstain spatter patterns. Bloodstain spatter patterns are not solely used to solve crimes but I do feel it is one of the most important. Bloodstains never lie. A bullet is traveling at its fastest speed when it leaves the barrel of the gun. Bullets traveling after firing is said to be using kinetic energy. Kinetic energy is the energy the bullet has due to its motion from the firing pin striking the gun powder causing an explosion that forced the bullet to discharge from the barrel. Now this bullet possess kinetic energy and will do harm to anything lying within its targeted path. (Kinetic Energy website) The kinetic energy given to bullets fried from rifles will be a higher velocity then that of a pistol or shot gun. Rifles barrels are longer and constructed to with stand more pressure and thus leading to a greater velocity of kinetic energy on a bullet (Warlow 67). Death can occur from firing a bullet straight up in the air. When the bullet is returning to the earth due to the gravitational pull it will pick up velocity. However the bullet can return either base or head side up (89). Powders also have different burning rates for different guns. When you have a longer barrel your burning rate of powder will be longer but if your barrel is shorter then you will have a faster...

Defence in Australia

...Military Technology Land Force Air And Missile Defence Dealing With The Complexities Of Future Warfighting Lieutenant Colonel Inger Lawes Abstract In the future, land force commanders will need to manage the use of airspace to enable multidimensional manoeuvre—coordinating joint and coalition assets and denying adversaries. Battlespace management, in an era of uninhabited and automated systems, is becoming increasingly complex. The author argues for the development of a ‘land force air and missile defence’ (LFAMD) to enhance friendly capability and defeat conventional and asymmetrical enemy manoeuvre. Introduction T he Australian Defence Force (ADF) Future Warfighting concept asserts that ‘the challenges of complex environments reinforce our view that warfare is multi-dimensional.’ 1 In future warfare, because of the presence of both conventional and asymmetric air threats, air and missile defence will become an essential capability in enabling the land force to conduct multi-dimensional manoeuvre.

Anglo Saxon Fighting Research Paper

...Have you ever wondered what the differences and similarities between Anglo-Saxon fighting, also known as Teutonic fighting, and Celtic fighting are? Well I am about to tell you. The Teutonic style of fighting was used by the Union, and the Celtic style of fighting was used by the Confederacy. So the differences and similarities are the Union wore body armor while the Confederacy did not worry about wearing body armor, they both fought with swords and spears, also they had shields to protect themselves other than just armor. Lastly the Celtic style of fighting was wild and savage-like, while the Teutonic style of fighting was more civilized. Tacitus, an Ancient Roman senator, has told us “They choose their kings for their noble birth, their leaders for their valor. The power even of the kings is not absolute or arbitrary. As for the leaders, it is their example rather than their authority that wins them special admiration - for their energy, their distinction, or their presence in the van of fight..... 'No business, public or private, is transacted except in arms. But it is the rule that no-one shall take up arms until the tribe has attested that he is likely to make good. When the time comes, one of the chiefs or the father or a kinsman equips the young warrior with shield and spear in the public council. This with the Germans is the equivalent of our toga - the first public distinction of youth. They cease to rank merely as members of the household and are now members of the...

Satellite Defence System

...SATELLITE MISSILE DEFENCE SYSTEM Introduction. 1. United States of America has conducted extensive research and development on various types of missile defense technologies for decades. In December 2002, President Bush announced the United States would begin fielding several components of an anti-missile system designed to protect U.S. territory from attack by long-range (strategic) ballistic missiles under the project termed as National Missile Defence System. In July 2004, it fielded the first ground-based interceptor at Ft. Greely, Alaska, and since then has fielded and upgraded radars, built command and communication networks, and added interceptors at various Air Force Base inside USA and also pressing to field interceptors and a radar in Eastern Europe. 2. Hence, National missile defense (NMD) is a generic term for a type of missile defense intended to shield an entire country against incoming missiles, such as intercontinental ballistic missile (ICBMs) or other ballistic missiles. Interception might be by anti-ballistic missiles or directed-energy weapons such as lasers. Interception might occur near the launch point (boost phase), during flight through space (mid-course phase), or during atmospheric descent. 3. The system would use ground-based radars and space-based infrared and visible sensors, and the kill vehicle would be equipped with infrared and visible sensors intended to destroy targets by colliding with them in the mid-course of their trajectory...
