Question
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?
Express your answer with the appropriate units. Enter positive value if glider BB is moving to the right and negative value if glider BB is moving to the left.
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?
Express your answer with the appropriate units. Enter positive value if glider AA is moving to the right and negative value if glider AA is moving to the left.
