A mass m1 = 15.0 kg and a mass m2 = 11.5 kg are suspended by a pulley that has a radius of 10.2 cm and a mass of 3 kg (see figure). The cord has a negligible mass and causes the pulley to rotate without slipping. The pulley rotates without friction. Treating the pulley as a uniform disk, determine the tension in the left cord?
