A 0.157 kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.900 m/s. It has a head-on collision with a 0.304 kg glider that is moving to the left with a speed of 2.21 m/s. Suppose the collision is elastic.
A) Find the magnitude of the final velocity of the 0.157kg glider.
B) Find the magnitude of the final velocity of the 0.304 kg glider.
