A girl is using a rope to pull a mystery box that has a mass of 30.6 kg across a rough level surface. The rope makes an angle with the floor of 30 degrees above the horizontal, and the tension in the rope is 100 N. If the coeficcient of kinetic friction between the box and surface is 0.333, what is the magnitude of kinetic friction force acting on the mystery box?
