When you apply a horizontal force of 54 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 48 N to the block initially at rest?
The block decelerates (the speed continually decreases).
The block doesn't move.
The block moves at a constant speed, but it moves more slowly.
(b) When you apply a force of 48 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?
Fhor = N
(c) What happens if instead you exert a force of 63 N?
The block accelerates (the speed continually increases).
The block moves at a constant speed, but it moves faster.
The block doesn't move.
(d) When you apply a force of 63 N, what is the magnitude of the horizontal component of the force that the floor exerts on the block?
Fhor = N
