A baseball player hits a baseball (m = 0.145 kg) The ball is initially traveling horizontally with speed of 36 m/s. The batter hits a fly ball as shown, with a speed vf = 54 m/s.
(a) What is the magnitude and direction of the impulse imparted to the ball?
(b) If the ball (m = 0.145 kg) and bat are in contact for a time of 8.4 ms, what is the magnitude of the average force of the bat on the ball?
Compare this answer to the weight of the ball.
The contact force is 4 times the ball's weight.
(c) What is the impulse imparted to the bat?
