Question

A baseball is pitched at 42 m/s. The bat is moving 40 m/s in exactly the opposite direction to the ball immediately before the impact. After the impact, the bat is slowed to 38 m/s while the ball is moving at 60 m/s in the direction the bat was swinging. What is the coefficient of restitution?

Answer 1

so  

e = (60-38) / (40 +42) =0.268292683 answer

Good Luck !!
