Physics problem

A Uniform pool ball mass 'm' and raidus 'r' begins at rest. It is given horizontal impulse J of fixed magnitude at a distance br above its center where -1<=B<=1. Coefficient of kinetic friction between ball and table is u. Assume both ball and table are rigid. Find an expression for the final speed in terms of J, m, and B

did you try using torque?

Man I hated these questions.

Good thing I'm in biology with all the hot girls now.

I was never very good in psychics class.

I know.

Challenge your Physics professor to come up with a list of things that are shape-invariant over volume changes.
