I don't think that's going to read very well, so check out here: http://en.wikipedia.org/wiki/Momentum
What's going to be the interest in the next hour?

I've been research elastic collisions... and yes, we are talking like two steel balls, no marshmellows. I am looking at the page you linked, and much like I always felt in school, its too much to take in- could you plug my numbers into a formula? Please? You know you want to show just how smart you are...
