Problem
A 0.40kg rubber ball strikes a rigid vertical wall horizontally at 6.0ms−1 and rebounds directly back along the same line. During the 0.010s contact with the wall, 25% of the ball’s initial kinetic energy is converted to internal energy and sound.
(i) Calculate the magnitude of the impulse delivered to the ball by the wall.
(ii) Determine the average rate at which energy is dissipated during the collision.
