A 2.0-kg block of wood is on a level surface where μs and μk = 0.60. A 13.7-N force is being applied to the block parallel to the surface.
a. If the block was originally at rest, then
1. it will remain at rest, and the force of friction will be about 15.7 N.
2. it will remain at rest, and the force of friction will be about 13.7 N.
3. it will remain at rest, and the force of friction will be 11.8 N.
4. it will begin to slide with a net force of about 1.9 acting on the block.
b. If the block was originally in motion, and the 13.7-N applied force is in the direction of motion, then
1. it will accelerate under a net force of about 1.9 N.
2. it will move at constant speed.
3. it will decelerate under a net force of about 1.9 N.
4. it will decelerate under a net force of 11.8 N.
