A box is pushed across a rough horizontal floor by a force acting parallel to the floor in the direction of motion. A force doing negative on the box is------
1. gravity
2. friction
3. the applied force
4. normal force of the floor upward on the body

Expert Solution

Summary: I applied formula for the work fone to calculate work due to all given forces in the options. And it came out that work due to frictional force is negative.

a force of 35N is required to start a 6kg box moving across a horizontal concrete floor. (a) what is the coefficient of the static friction between the box and floor? (b) if the 35N force continues the box accelerates to 0.60m/s2. what is the cowfficient of the kenetic friction

Since the floor is rough, it exerts both a normal force N1 and a frictional force...

Since the floor is rough, it exerts both a normal force N1 and a frictional force f1 on the ladder. However, since the wall is frictionless, it exerts only a normal force N2 on the ladder. The ladder has a length of L = 4.1 m, a weight of WL = 58.5 N, and rests against the wall a distance d = 3.75 m above the floor. If a person with a mass of m = 90 kg is standing...
