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

One is supposed to find the velocities after the collision perhaps?

What is the significance of the elastic collision?

Here's some useful information -
