thanks :) but i can't see anything about the 1 in 90 bit, can someone explain that?

1. Are your notes really missing :P. 2. If you have the mass and speed of an object you can compute it's energy. If you know that it loses energy through climbing and friction (or whatever that is) in a constant manner than time is easy. 3. This is a plastic collision problem and energy will...
