Blocks A, B, and C are placed as in the figure and connected by ropes of negligible mass. Both A and B weigh 27.5 each, and the coefficient of kinetic friction between each block and the surface is 0.40. Block C descends with constant velocity.
Find the tension in the rope connecting blocks A and B. What is the weight of block C? If the rope connecting A and B were cut, what would be the acceleration of C?
