A golf ball m = 0.135 kg strikes a vertical concrete wall elastically with a horizontal velocity of v = 17 m/s.
Part (a) Write an expression for the magnitude of the impulse I experienced by the ball.
Part (b) If the ball was in contact with the wall for t = .1s, what is the magnitude of the force F the ball experienced in N?
Part (c) If the ball rebounds with only half the velocity it comes in with, what is the magnitude of the impulse in kg m/s?
Part (d) How much kinetic energy was lost in the above situation in joules?
