The picture above shows a paintball gun that can fire a paintball with different initial velocities. A student shoots the paintball gun across level ground, and notices that
the paintball takes a certain amount of time to hit the ground when it is at a low
velocity. Explain why the student would expect the paintball would take the same
amount of time to hit the ground when it is fired with a higher initial velocity.

(a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
