### Investigation of Elastic collisions of frictionless gliders

A 0.143 kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.840 m/s. It has a head-on collision with a 0.303 kg glider that is moving to the left with a speed of 2.25 m/s . Suppose the collision is elastic. Alright, I used the conservation of kinetic energy on this one and I have two var
