Pulley Having Mass

A 15.0 kg object and a 10.0 kg object are suspended joined by a cord that passes over a pulley with a radius of 10.0 cm and a mass of 3.00 kg . The cord has a negligible mass and does not slip on the pulley . The pulley rotates on its axis without friction . The objects start from rest 3.00 m apart . Treat the pulley as a uniform disk , and determine the speeds of the two objects as they pass each other .
