The problem is that, in physics 1000, we always assumed our rolling motion was on a surface, allowing us to relate the linear speed to the rotational speed.

Initially I thought I would just ignore the fact that both types of motion would apply, but I then figured the sum of rotational and linear energy had to stay constant (subtracting out work done, of course).

So I guess it boils down to: if I have an object with moment of inertia I and apply a forward impulse a distance R to the right, how will it react?
