# Glider problem?

A glider of mass 0.152 kg is moving to the right on a frictionless, horizontal air track with a speed of 0.820 m/s. It has a head-on collision with a glider 0.298 kg that is moving to the left with a speed of 2.25 m/s. Suppose the collision is elastic.

Find the magnitude of the final velocity of the 0.152 kg glider.

Find the magnitude of the final velocity of the 0.298 kg glider.

okay so i used this formula :

v1f=((m1-m2)/(m1+m2))v1i +((2m2)/(m1+m2)v2i

Again use the conservation of momentum and conservation of energy (because it is an elastic collision) and solve the two simultaneous equations that are created for the final velocity of glider 1 and glider 2.
