This, in turn, is used to calculate the rpms from the surface speed. In this example, we clearly want the effective diameter to be the whole diameter of the ballnose and entering that full depth as in the definition makes that clear.  ### [Physics] How to calculate rebound speed of ball hitting a ...

A ball of mass is travelling horizontally with a speed of m/s. It strikes a vertical wall and rebounds horizontally. Due to the collision with the wall, 20% of the ball's initial kinetic energy is dissipated. Show that the ball rebounds from the wall with a speed of m/s.  ### Ballnose Cut Depth Musings for Feeds and Speeds in G ...
