1. If I subtract the last position from the current position position, would that vector be its current velocity?

 

2. If I used some trig to calculate the angle between the last and current position, would that satisfy the Alpha and Gamma?

 

 

 

1.1 Negating deformation, if the ball hits a surface with a CoR of say 0.9 and the ball has a CoR of say 0.92, will I use an average of the two, e.g. 0.91 * the velocity from 1?

 

2.1 Negating spin, if I have the approach angle relative to the normal of the surface, will the exiting angle be a reflection of this angle of incidence? (or was that just a drunken night playing pool and seeing double?)... and how to do using two vectors?
