Collision of two initially moving objects

  1. Jul 11, 2014 #1
    So I know how to solve for two initially moving objects that collide one way, but I was reading on this website another way to do it and I am not understanding a step. I've included a picture of the site and underlined the step I don't understand. I've tried a couple ways but I can't get it.

    Here is the link the the site as well


    Thanks for reading.

    "It is easily demonstrated that"... a bunch of equations that result.
    YOu should be able to work backwards from the equations - you have to apply the transform to com frame as suggested and then work through the consequences of conservation of momentum.
