5.31 . You are lowering two boxes, one on top of the othe down the ramp shown in Fig. E5.31 by pulling on a rope parallel the surface of the ramp. Both boxes move together at a consta speed of 15.0 cm/s. The coefficient of kinetic friction between tt ramp and the lower box is 0.444, and the coefficient of static fri tion between the two boxes is 0.800. (a) What force do you need exert to accomplish this? (b) What are the magnitude and directic of the friction force on the upper box? Figure E5.31 32.0 kg 48.0 kg 2.50 m
