Question

A sled on ice moves in the way described . 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. Which force would keep the sled moving toward the right and speeding up at a steady rate (constant acceleration)

Answer 1

The question is not complete, so i have attached an image of the complete question and the image of the sled on the ice.

Answer:

A) 3

B) 7

C) 5

D) 5

E) 5

Step-by-step explanation:

A) Looking at the image attached, The force that will continue to move the sled toward the right and speeding up at a steady rate would have to be a force acting towards the right and has constant strength (magnitude).

Thus, option 3 is correct.

B) The force that will continue to move the sled toward the right and at Constant velocity will be when no force is applied because at constant velocity, acceleration is zero and thus force will also be zero.

Thus, option 7 is correct.

C) The force that will slow the sled when moving to the right at steady rate(constant acceleration) would be an opposite force which means a force towards the left with a constant strength (magnitude).

Thus, option 5 is correct.

D) The force exerted on the sled by a person when the sled is accelerating to the right would be the normal force exerted on the person by the ice).

Thus, option 5 is correct.

E) The reaction to the normal force exerted on the sled by the ice when the sled is accelerating to the left would be the normal force exerted by the sled on the ice

Thus, option 5 is correct
