A 0.150kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.710m/s . It has a head-on collision with a 0.291kg glider that is moving to the left with a speed of 2.19m/s . Suppose the collision is elastic.
A. Find the magnitude of the final velocity of the 0.150 kg glider.
B. Find the direction of the final velocity of the 0.150 kg glider.
