Two gliders are on a frictionless, level air track. Both gliders are free to move. Initially, glider A moves to the right and glider B is at rest. After the collision, glider A has reversed direction and moves to the left. The mass of glider A is one quarter of the mass of glider B. The system is defined as the two gliders.   Which object has the higher change in momentum? A Glider A B Glider B C They have the same change in momentum in both magnitude and direction D They have a change in momentum that is equal in magnitude but opposite in direction E Cannot determine
