Consider the figure shown in the following figure. You are lowering two boxes, one on top of the other, down a ramp by pulling on a rope parallel to the surface of the ramp. Both blocks move with constant velocity. The coefficient of kinetic friction between the ramp and the 18.0 kg lower box is 0.452 and the coefficient of static friction between the 27.0 kg two boxes is 0.770. 3.50 D. What is the magnitude of the applied force? 5.75 E. Determine the angle at which the top block will start to slide down the bottom block. m
