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.

____ 1. Which force would keep the sled moving toward the right and speeding up at a steady rate (constant acceleration)?

____ 2. Which force would keep the sled moving toward the right at a steady (constant) velocity?

____ 3. The sled is moving toward the right. Which force would slow it down at a steady rate (constant acceleration)?

____ 4. Which force would keep the sled moving toward the left and speeding up at a steady rate (constant acceleration)?

____ 5. The sled was started from rest and pushed until it reached a steady (constant) velocity toward the right. Which force would keep the sled moving at this velocity?

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

____ 7. The sled is moving toward the left. Which force would slow it down at a steady rate (constant acceleration)?

Explanation / Answer

ANSWER

1. Toward the right and is of constant strength
2. No applied force is needed
3. Toward the left and is of constant strength
4. Toward the left and is of constant strength
5. No applied force is needed.
6. Toward the right and is decreasing in strength
7. Toward the right and is of constant strength.
