When you apply a horizontal force of 50 N to a block, the block moves across the floor at a constant speed (μk = μs).

a. What happens if instead you apply a force of 41 N to the block initially at rest?

1. The block decelerates (the speed continually decreases).
2. The block doesn't move.
3. The block moves at a constant speed, but it moves more slowly.

b. When you apply a force of 41 N to the block initially at rest, what is the magnitude of the horizontal component of the force that the floor exerts on the block?
c. What happens if instead you exert a force of 53 N?

1. The block moves at a constant speed, but it moves faster.
2. The block doesn't move.
3. The block accelerates (the speed continually increases).

d. When you apply a force of 53 N, what is the magnitude of the horizontal component of the force that the floor exerts on the block?

Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.
