Magnitude of final velocity. Due today

  1. 1. The problem statement, all variables and given/known data

    A glider of mass 0.143 kg is moving to the right on a frictionless, horizontal air track with a speed of 0.750 m/s. It has a head-on collision with a glider 0.303kg that is moving to the left with a speed of 2.13 m/s. Suppose the collision is elastic.

    2. Relevant equations
    MaVa1+MbVb1=MaVa2+MbVb2
    1/2MaVa1^2+1/2MbVb1^2=1/2MaVa2^2+1/2MbVb2^2


    3. The attempt at a solution

    Where do I start with this? I have all of the left side of the equations, but nothing on the right
