A tennis player receives a shot with the ball (0.0600 kg) traveling horizontally at 56.6 m/s and returns the shot with the ball traveling horizontally at 34.8 m/s in the opposite direction. (Take the direction of the ball's final velocity (toward the net) to be the +x-direction.) (a) What is the impulse delivered to the ball by the racket? magnitude N · s (b) What work does the racket do on the ball? (Indicate the direction with the sign of your answer.)
