4) Bubba pulls two boxes across the floor of his barn. One box has a mass (m1) of 20.4 kg and has a coefficient of kinetic friction of 0.321 with respect to the floor. The second box has a mass (m2) of 23.1 kg and a coefficient of kinetic friction of 0.177 with respect to the floor. The two boxes are connected with a rope. Bubba pulls on another rope connected to the second box. All of the ropes are...
By pulling a on rope attached to a crate of mass 77.0 kg, the crate is dragged across a floor. Let the coefficient of static friction between the crate and the floor be 0.830 and the angle between the rope and horizontal is 39.1 °. Find the minimum force required to move the crate. At a later time the crate is now dragged with this same force, and has already started moving, on a wet floor where the kinetic friction...
MY NOTE Two blocks connected by a rope of negligible mass are being dragged by a horizontal force (see figure below).

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...
You pull on a stationary block of mass 150kg with a cord that makes a constant angle of 0.4712rad as measured up from horizontal. The coefficient of static friction between the block and the floor is 0.79 , and the coefficient of kinetic friction between the block and the floor is 0.35 . If you pull on the stationary block with a constant tension of magnitude 651.2N , how much net work will be done on the block after pulling for 4s...
