In the figure provided, two suitcases are on a 5.94 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 12.8 kg and the other suitcase has a mass of 25.6 kg, what is their combined speed if an inelastic collision is achieved? Assume the ramp to be frictionless.

If a rainstorm drops 1 cm of rain over an area of 10km2 in the period of 1 hour, what is the momentum of the rain that falls in one second? Assume the terminal velocity of a raindrop is 10 m/s.
A superball of mass M and a marble of mass m are dropped from a height h with the marble just on top of the superball.

The superball collides with the floor, rebounds, and smacks the marble, which moves back up. How high does the marble go if all the motion is vertical? How high does the superball go?
