Exercise 5.31You are lowering two boxes, one on top of the other, down the ramp shown in the figure (Figure 1) by pulling on a rope parallel to the surface of the ramp. Both boxes move togetherat a constant speed of 12.0cm/s . The coefficient of kinetic friction between the ramp and the lower box is 0.500, and thecoefficient of static friction between the two boxes is 0.783.Part AWhat force do you need to exert to accomplish this?
