Find the unknown mass of the block

Reference no: EM13333909

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 2kg and radius 5cm, and the other block's mass is unknown. The blocks are released from rest, and after an unspecied period of time, the block of known mass has descended 2:5m and has a velocity of 3m=s toward the ground. The rope does not slip over the pulley, and the pulley spins on a frictionless axle. Find the unknown mass of the block.
