As shown in figure below a box of mass (60 kg) being pulled with a rope on a rough horizontal floor. magnitude of the applied force is (400 N) and the rope makes a (30°) angle with horizontal. The box mo at a constant speed. • Find the coefficient of kinetic friction between the box and the floor. • How much work is done on the box by the person in moving the box over a horizontal distance (11 m • Find the work done by the force of friction over the same distance. • What is the total work done on the box?
