I don't remember learning this in my C Physics Mechanics class which is odd since it seems pretty important. In the case where you have one object colliding with another object off its center of mass, how do you tell how much of the energy from the collision goes into rotational kinetic energy and how much of it goes into translational kinetic energy?
Thanks for the help.

Hi Stucky! Welcome to PF!
There's no straightforward method. You work it out from the conservation of momentum and of angular momentum , together with some lossofenergy equation determined by experiment, that usually gives the mechanical energy lost as a proportion of total mechanical energy.
