Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I'm trying to figure out how to calculate the resulting velocity vector of a ball after impact with a surface.

If the velocity vector is V {Vx, Vy, Vz} and The ball hits a surface with normal N {Nx, Ny, Nz} what would be the resulting vector of the new velocity?

Assuming the ball has an elasticity coefficient 0 <= k <= 1.

The angle of incidence won't be equal to the angle of reflection would it?

As an example V could be {0, -10, 0} and N {0, 1, 0}

Thanks.
