Homework Help: Momentum and Collision Lab

  1. Nov 23, 2009 #1
    1. The problem statement, all variables and given/known data
    This is a lab, I think I want to find if momentum is conserved after collision (data for proof).

    2. Relevant equations
    Change Y = Vit + .5at^2

    3. The attempt at a solution
    I found that time is equal to 0.515 seconds from using that equation.

    -1.3M = 0 + .5(-9.8m/s^2)t^2

    I don't know what to do next... I got the distance where the balls collide and landed, and where the it would originally land if it didn't collide.
