A glider of mass 0.155 is moving to the right on a frictionless, horizontal air track with a speed of 0.730 . It has a head-on collision with a glider 0.299that is moving to the left with a speed of 2.20 . Suppose the collision is elastic.
(a) Find the magnitude of the final velocity of the 0.155 glider.
(b) Find the magnitude of the final velocity of the 0.299 glider.
