A tennis player swings her 1000 g racket with a speed of 8.0 m/s . She hits a 60 g tennis ball that was approaching her at a speed of 21 m/s . The ball rebounds at 37 m/s .

1. How fast is her racket moving immediately after the impact? You can ignore the interaction of the racket with her hand for the brief duration of the collision.

2.If the tennis ball and racket are in contact for 8.0 ms , what is the average force that the racket exerts on the ball?
