A golf gall is dropped from a height of h1 = 3.45 m. After it bounces it only reaches h2 = 2.23 m. The golf ball has mass m =0.146 kg
Part (a) What is the magnitude of the impulse I the golf ball experienced during the bounce in kg m/s?
Part (b) If the golf ball was in contact with the ground for t = 0.119 s what was the magnitude of the constant force acting on it F in N?
Part (c) How much energy did the ball transfer to the environment during the bounce in Joules?
