    Coefficient of Restitution problem

    Could you explain that statement. I thought the difference between speed and velocity is that velocity considers direction?

    Velocities since it says 'in the opposite direction' I'm assuming.

    Coefficient of Restitution problem

    Hello, I have this simple COR problem that I seem to be a bit stuck on. Homework Statement 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...
