4 3. You are lowering two boxes, one on top of the other, down the ramp by pulling on a rope parallel to the surface of the ramp, as shown in the figure. Both boxes move together at a constant speed of 15.0 cm/s. The coefficient of kinetic friction between the ramp and the lower box is 0.444. The boxes are 32.0 kg (the top), and 48.0 kg (the bottom). (a) Draw free body diagram for each box separately. (b) What force do you need to exert to accomplish the task? 57.1 N (c) What are the magnitude and direction of the static friction force on the upper box? 146 N parallel to the incline and upward 32.0 14 48.0 ka 4.75 m 2.50
