Read Details15 Points For the following questions, refer to the diagram and explain your answers. a. What is the velocity of the object at 2.5 seconds? b. What is the average speed over the first 3 seconds? c. Is the object ever at rest? If so, when? d. What is the displacement of the object from 0-6 seconds? e. Determine the position of the object at 4 seconds.
Read DetailsQuestion 3 (10 Points) A small can is hanging from the ceiling. A rifle is aimed directly at the can, as illustrated in the diagram. At the instant the gun is fired, the can is released. Ignored wind resistance and show that the bullet will always strike the can, regardless of the initial speed of the bullet. (Assume that the bullet strikes the can before the can reaches the ground)
Read DetailsQuestion 4 (15 Points) The drawing shows an exaggerated view of a rifle that has been “sighted in” for a 91.4 meter target. If the muzzle speed of the bullet is vo = 427 m/s, what are the two possible angles between the horizontal and the barrel such that the bullet will hit the target? (One is so large that it would never be used in target shooting)
