One glider with a mass 0.2 kg and a speed of 3.5 m/s traveling east collides with another glider with mass 0.5 kg and a speed of 2.0 m/s moving west. They collide and stick together.
Calculate the net mechanical energy and is it a loss or gain?
Answered by drwls
Use momentum conservation to get the final velocity. Then calculate the new mechanical energy. See for yourself if mechanical energy is lost or gained.
