A 0.400 kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.900 m/s when it makes a head-on collision with a stationary 0.150 kg glider.
a) Find the magnitude of the final velocity of second glider if the collision is elastic.
b) Find the final kinetic energy of first glider.
c) Find the final kinetic energy of second glider.
