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 taking the derivative respect to theta. Please explain in great detail how this is done and all the reasoning behind it not just an equation and solving a derivative. Please I need to picture this graphically and understand what is happening. please paint a good picture.
thank you

A 15.0 kg box is being pulled across a rough floor at a constant acceleration of 3.00 m/s^2 by means of a rope. The rope makes an angle of 34.0 degrees above the horizontal. The coefficient of kinetic friction between the floor and the box is u=0.250. Calculate the magnitude of the tension in the rope?

In the sport of parasailing, a person is attached to a rope being pulled by a boat while hanging from a parachute-like sail. A rider is towed at a constant speed by a rope that is at an angle of 15 ∘ from horizontal. The tension in the rope is 1900 N. The force of the sail on the rider is 30∘ from horizontal. What is the weight of the rider? Express your answer with the appropriate units. Include a...
