Two gliders are moving to the right on an air track. The one to the right is moving at a speed of 2V0 and has a mass of 2M. The one to the left is moving at a speed of 3V0 and has a mass of M. The collision among the two gliders is elastic. What are the final velocities of the two gliders? Start from the basic conservation laws and work during the algebra. You might use the relative speed result we derived for this case..
