Hope this helps :)
two suitcases are on a 7.89 m high ramp to passengers waiting in a baggage terminal. The top suitcase is released from rest, and it slides down the ramp and hits the second suitcase. If the suitcase at the top has a mass of 16.6 kg and the other suitcase has a mass of 33.2 kg, what is their combined speed if an inelastic collision is achieved? Assume the ramp to be frictionless.
