A tennis player receives a shot with the ball (0.0600 kg) traveling horizontally at 50.0 m/s and returns the shot with the ball traveling horizontally at 38.0 m/s in the opposite direction. (Assume the initial direction of the ball is in the -xdirection.)
(a) What is the impulse delivered to the ball by the
racket?
(b) What work does the racket do on the ball?

A tennis ball of mass 0.0600 kg is initially moving horizontally with a speed of 25.0 m/s. A tennis player hits it with his racket with an average force of 66 N, sending the ball back in the opposite direction with a speed of 35.0 m/s. For how much time was the racket and ball in contact, in units of seconds?

7. On a serve, a tennis ball may leave the tennis racket of a top player at a speed of 65.0 m/s. If the ball has a mass of 0.0600 kg and it is in contact with the racket for 0.0300 seconds, what is the average force applied to the ball? Would that be enough force to lift an average size person (75 kg)? Assume that the tennis ball is initially not moving
