Making a logo spin around when bouncing off a wall

(Using Flash MX) Alright, I finished not too long ago the templated ball that you pick up and throw around and it's really neat and it bounces and some good stuff. Well, I had the thought a little while ago to do that with a logo but instead to make it spin. The only problem that I have is since i'm not a math wizard, I don't really know everything behind the physics to make it do that. Mind you I just want it to spin 2 demensionally, none of this 3D action that plasma can do in it's spare time :D. So I was wondering since I understood some of the script for the ball bouncing around if someone would be able to help me or in the very least point me in the right direction, that would be great.
