Two rail cars roll without friction on a track. The rail cars have different masses. The heavier car is at rest. The lighter car is moving with speed v, hits the heavier car, and sticks to it. The combined two-car system then moves with speed v/5. What is the ratio of masses of the two cars? Ratio = mass of heavier car / mass of lighter car.
