Hey everyone, I'm having trouble on a homework problem and hopefully someone can help me.(adsbygoogle = window.adsbygoogle || []).push({});

A tennis player receives a shot with the ball (0.0600 kg) traveling horizontally at 58.0 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 -x direction.)

(a) What is the impulse delivered to the ball by the racquet?

(b) What work does the racquet do on the ball?

I was able to get (a), but (b) is stumping me. I know momentum is conserved, but they don't provide any mass information on the racquet so I'm confused. Any help is appreciated.
