N horses, each of mass m, stand on a train whose mass is M. They jump off one end of the train with velocity v relative to the train. The train was at rest initially. Then, the train moves in the opposite direction without any friction. Solve the following questions:
A What is the final velocity of the train if all the horses jump at the same time?
B What is the final velocity of the train if the horses jump off one by one?
C Which final velocity in the above is larger?

Two friends, Al and Jo, have a combined mass of 168 kg. At an ice skating rink they stand close together on skates, at rest and facing each other, with a compressed spring between them. The spring is kept from pushing them apart because they are holding each other. When they release their arms, Al moves off in one direction at a speed of 0.75 m/s, while Jo moves off in the opposite direction at a speed of 1.5 m/s....

A lumberjack (mass = 98 kg) is standing at rest on one end of a floating log (mass = 275 kg) that is also at rest. The lumberjack runs to the other end of the log, attaining a velocity of +3.5 m/s relative to the shore, and then hops onto an identical floating log that is initially at rest. Neglect any friction and resistance between the logs and the water. (a) What is the velocity of the first log just...

A block of ice of mass m and a wedge of ice of mass M can slide on one another and on a horizontal ice surface without friction. Initially the wedge is at rest and the block moves towards it with speed upsilon_0. When the block reaches the wedge, it slides up the slope to a maximum height, h above the horizontal. It then descends and returns to the horizontal surface. What is the height, h reached by the block?...
