A 0.141 kilogram glider is moving to the right on a frictionless, horizontal air track with a speed of 0.850 m/s. It has a head-on collision with a 0.309 kilogram glider that is moving to the left with a speed of 2.20 m/s. Assume the collision is elastic.
Part A) Compute the magnitude of the final velocity of the 0.141 kg glider.
Part B) Compute the magnitude of the final velocity of the 0.309 kg glider.
