A tennis player receives a shot with the ball (0.0600 kilogram) traveling horizontally at 54.0 m/s and returns the shot with the ball traveling horizontally at 30.0 m/s in the opposite direction. (Suppose the initial direction of the ball is in the -x direction.)
(a) Find the impulse delivered to the ball by racket?
N•s2
(b) Estimate what work does the racket do on the ball?
J
