Physics

As an unbiased investigator, we amaze nothing but the tapes and go away train little to no heed on the deposition of the witness. We leave behind rely solely on physics to answer this problem. The face that get outing break the innocence of suspect, Bert, volition be to father out what the initial speed of the bullet was when it left the jacket crown of the building. From this reading, we testament be open to tell if the can buoy was throw deliberately, or accidentally dropped. In order to examine this problem, we leave alone have to look at it from deuce different perspectives. The starting signal aspect will circle with the x-direction and the punt will deal with the y direction. By victimisation the footage captured by a escape Valentine, we will regulate the fastness initial in two directions and hence, using this information, attain a resultant speeding initial. plot of incident: succinct of Method:             Â Â Â Â Â Â To deal with this problem, we will have to use the footage to sire a final f number at the bottom of recede Valentines window. Because of the mass of the pot, and the calmness of the weather on August 5, 2000, we will foreshorten any wind resistance that was involved. For this reason, the acceleration that the pot undergoes, regardless of its initial focal ratio is 9.8 meters/second (acceleration due to gravity).         We will use the equation:         This will determine the final velocity (at the bottom of Miss Valentines window. We will then use this information and this equation to pass what the initial velocity at the go along of the building was too large to be an accident. The equation is as follows:          The final step will be to combine the two vectors, and influence a resultant magnitude, using Pythagoreans theorem. X-Direction:         From the video, we can throw that there was n o displacement in the x-direction. For this ! reason, we will ignore this aspect of the problem, and determine the initial velocity as it applies to the y-direction. Y-Direction:                   rive 1: Distance Traveled: 90 centimeters Total duration: .075seconds ( Found this using the frames/second and the take of frames) acceleration: 9.8 meters/second/second                  Using this information, we will instantaneously find the velocity initial. Velocity Final: 15.7 meters/second X-final: 8.4 meters (Distance from ceiling to excrete of Miss Valentines window plus length of windows) X-initial: 0 meters Acceleration: 9.8meters/second/second Conclusions:         From this information we found that the initial velocity was approximately equal to 9.1 meters per second. If this was an accident, it would be reasonable to count that the initial velocity was somewhere in the vicinity of 0 to .5 meters per second. But, from the evidence, w e find that this was not the case, and in fact was much exalteder(prenominal) than this. For this speed to be the case, then , there had to be a lot of might given initially, and thus producing a high initial velocity. For this reason, we will find Bert guilty for the murder of Edward Hooper. If you hope to get a full essay, order it on our website: BestEssayCheap.com
