# Inelastic collision (not homework)

Note: This is not a homework problem (it is far too advanced for a suitable homework problem). So don't move it to the homework category as that would not lead to interesting replies/attempts to solve this problem. This is simply a discussion problem for everyone here to think about.

Consider two balls. Ball i has radius Ri, mass Mi, elasticity modulus Ei and Poisson ratio $$\nu_i$$. Ball 1 moves at velocity v relative to ball 2 and has an impact parameter of zero. Both balls have an angular momentum of zero.

Compute (or estimate) the amount of internal energy of both balls that will be generated as a result of the collsion (this will eventually be dissipated, of course).
