A 200 kg sled that is 40m long is sliding eastward at a speed of 5 m/s relative to the icy ground below. A 60 kg human is standing at the eastern edge of the sled and suddenly begins running westward at a constant speed of 10 m/s relative to the center of mass of the system that consists of the sled and the human.

1) Explain why the sled speed increase after the human starts to run.

2) Determine the sled speed relative to the ground while the human is running

The human now instantly comes to rest relative to the sled when he reaches the sled’s western edge

3) Determine time it takes for human to reach western edge of sled from east side

4) Determine ratio of the distance the sled has moved relative to the icy ground, to the distance the sled would have moved if the human had just remained at rest on the east side
