A tennis player swings her 1000 gram racket with a speed of 11 m/s. She hits a 60 gram tennis ball that was approaching her at a speed of 17 m/s. The ball rebounds at 36m/s.
(a) Determine how fast is her racket moving immediately after the impact? You can neglect the interaction of the racket with her hand for the brief duration of the collision.
m/s
(b) If the tennis ball and racket are in contact for 10 milliseconds, evaluate the average force that the racket exerts on ball?
N
(c) Determine how does this compare to the ball's weight?
Favg / Wball =
