Three blocks are connected as shown. The ropes and pulleys are of negligible mass. When released, block C moves downward, block B moves up the ramp, and block A moves to the right. After each block has moved a distance d, the force of gravity has done: A. positive work on A, B, and C. B. positive work on A and B, and negative work on C. C. zero work on A, positive work on B, and negative work on C. D. zero work on A, negative work on B, and positive work on C.
