A) You hold glider AA of mass 0.125 kgkg and glider BB of mass 0.375 kgkg at rest on an air track with a compressed spring of negligible mass between them. When you release the gliders, the spring pushes them apart. Once the gliders are no longer in contact with the spring, glider AA is moving to the right at 0.600 m/sm/s. What is the velocity (magnitude and direction) of glider BB at this time?
B) Glider AA moving to the right at 0.600 m/sm/s then collides head-on with a third glider CC of mass 0.750 kgkg that is moving to the left at 0.400 m/sm/s. After this collision, glider CC is moving to the left at 0.150 m/sm/s. What is the velocity (magnitude and direction) of glider AA after this collision?
C) Two hockey players skating on essentially frictionless ice collide head-on. Madeleine, of mass 65.0 kgkg, is moving at 6.00 m/sm/s to the east just before the collision and at 3.00 m/sm/s to the west just after the collision. Buffy, of mass 55.0 kgkg, is moving at 3.50 m/sm/s to the east just after the collision. Find Buffy’s velocity (magnitude and direction) just before the collision.
D)What is the change in the velocity of Madeleine during the collision? Take east to be the positive direction.
