Question 3 a)

A

fastpitch softball player swings her 600 g bat with a speed of 25 m/s at the

time of impact with the ball. She hits a 170 g softball that was approaching

her at a speed of 30 m/s. The ball rebounds at 41 m/s.

How

fast is her bat moving immediately after the impact? (Ignore the interaction

with her hand for the duration of the collision.)
