Apaintball’s mass is 0.0032kg. a typical paintball strikes a target moving at 85.3 m/s.
a) if the paintball stops completely as a result of striking its target, what is the magnitude of the change in the paintball’s momentum?
b) if the paintball bounces off its target and afterward moves in the opposite direction with the same speed, what is the magnitude of the change in the paintball’s momentum?
c) the strength of the force an object exerts during impact is determined by the amount the object’s momentum changes. use this idea along with your answers to (a) and (b) to explain why a paintball bouncing off your skin hurts more than a paintball exploding upon your skin.
