Two blocks hang from either end of a massless rope that runs over a pulley, treated as a thin solid disk, (An Atwood's Machine), and are held in place. One block has a mass of 12kg, the pulley has a mass of 4kg and radius 10cm, and the other block's mass is unknown. The blocks are released from rest, and the block of known mass accelerates toward the ground at a rate of 1m=s2. The rope does not slip over the pulley, and the pulley spins on a frictionless axle. Find the unknown mass of the block.
