2. A 3.80-kg hanging block is pulling against a 2.50-kg block on a tabletop, as shown, via a string over a pulley that is massless and frictionless. At the same time, a constant external force F = 5.50 N is pulling the tabletop block to the right, as shown. There is a static friction coefficient is = 0.75, and kinetic friction coefficient dx = 0.15, with the tabletop. (a) The blocks are initially stationary. With a calculation, determine whether the...

You are pulling a 6.8 kg box with rope with a force of 5.5 N. The rope is 35° above thehorizontal. For a while you are pulling across ice that is very smooth. Later you reach a patch of snow which has a kinetic coefficient of friction of 0.2 and a static coefficient of friction of 0.35 with the box. A)Draw the free body diagrams for the box when it is on the ice and when it is on the...
