A tennis player receives a shot with the ball (0.060 0 kg) traveling horizontally at 50.0 m/s and returns the shot with the ball traveling horizontally at 40.0 m/s in the opposite direction.
a) What is the impulse delivered to the ball by the tennis racquet?
b) What work does the racquet do on the ball?
