Your Answer: As shown in the figure above, block A (mass 2.25 kg) rests on a tabletop. It is connected by a horizontal cord passing over a light, frictionless pulley to a hanging block B. The coefficient of kinetic friction between block A and the tabletop is 0.450. The blocks are then released from rest. When the blocks have moved 3.00 cm the tension in the cord is 13.5 N, what is the mass of block B? Note: Your answer is assumed to be reduced to the highest power possible. Answer A x10 B units
