Showing work (Perfectly Elastic Collision)

  1. Oct 6, 2009 #1
    1. The problem statement, all variables and given/known data

    Two pool balls hit head on. V(1) = 2.0 m/s west, V(2) = 5 m/s east. Mass is the same for each ball.

    2. Relevant equations

    3. The attempt at a solution

    m(1)*(-2m/s)^2 + m(2)*(5m/s)^2 =??? no idea...I just know that each ball should be going the same speed and direction as the other.

    I'm totally confused as to how I show work.




    Thank you for reading the probably & attempting to help even if you're not able to. I'm open eyes & ears to everyone.
