Blocks A, B, and C are connected using rope of negligible mass (see figure below). The coefficient of kinetic friction between each block and the surface is 0.25. Block C descends with constant velocity. a) Draw free body diagram for blocks A and B. b) Find tension in rope connecting blocks A and B. (I bet one of those free body diagrams would be helpful!) c) What is the mass of block C? (Ditto)
