Glider A with mass 0.400 kg, gliding with a velocity of magnitude 0.50 m/s on a frictionless, horizontal air track, makes a perfectly elastic head-on collision with a glider B with mass , initially at rest. After the collision, the velocity of the glider A is 0.1 m/s in a direction opposite to its initial velocity. Find the mass of the glider B.
