A horizontal force of 50 N pushes a box that weighs 75 N across the floor at a constant speed. The coefficient of kinetic friction between the box and the floor is 0.67.
a) Draw the free-body diagram for the box. Clearly label all of the forces that are present.
b) What is the magnitude of the frictional force acting on the box?
c) What is the power generated by the applied force if it takes 30 seconds to push the box 12 meters?
