Hello, I have this simple COR problem that I seem to be a bit stuck on.
A 1.25 kg squash racquet swung at 37 m/s contacts a ball moving at 42 m/s in the opposite direction. Immediately after impact the racquet has a velocity of 25 m/s and the ball has a velocity of 50 m/s. What is the coefficient of restitution associated with the impact?
I've been using e= (V1-V2)/(U1-U2)
When I use this equation I get 5, but obviously that's wrong since it shouldn't be greater than 1.
Can anyone point me in the right direction? Thanks so much
