A box is being pulled along a level floor at a constant velocity by means of a rope attached to the front end of the box. The rope makes an angle theta with the horizontal. Show that for a given mass m of the box and given coefficient of kinetic friction uk, the tension required in the rope is minimum if tan theta=uk. What is the tension in the rope when at this optimum angle? The answer I found show...

A block of mass = 50.0 kg is being dragged at a constant velocity across a floor by a strong person pulling it with a rope. The rope makes an angle of 300 with the horizontal. The tension in the rope is 50.0 Newtons. Assume a real floor, with friction. What is the coefficient of kinetic friction between the box and the floor?

I. A rope used to pull a 15 kg box across a level floor at a co nstant speed makes à 25o angle with the horizontal. The tension in the rope is 50 N. Determine the coefficient of friction between the box and the floor. (.359) 2. If the tension in the rope in the previous problem is increased to 100 N and the coefficient of friction stayed the same, what would be the new acceleration? (3.53m/s2)

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?
