Question

A sled on ice moves in the ways described in questions 1-7 below. Friction is so small that it can be ignored. A person wearing spiked shoes standing on the ice can apply a force to the sled and push it along the ice. Choose the one force (A through G) which would keep the sled moving as described in each statement below.

You may use a choice more than once or not at all but choose only one answer for each blank. If you think that none are correct, answer choice J.

6. The sled is slowing down at a steady rate and has an acceleration to the right. Which force would account for this motion?

Explanation / Answer

For the uppermost box, the direction of force is towards right and the force is constant in magnitude. [B]

For the middle box, there is no applied force [D]

For the lowermost box, the applied force is directed to left and is of constant magnitude [F].

6] The sled is decelerating to the right (deceleration is constant) and so the force is directed to left and is constant in magnitude [F].
