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.
