A 4.00-kg mass is connected by a light cord to a 3.00-kg mass on a smooth surface. The pulley rotates about a frictionless axle and has a moment of inertia of 0.450 kg·m2 and a radius of 0.290 m. Assuming that the cord does not slip on the pulley, find the magnitude of the acceleration of the two masses.And find the tensions T1 and T2.
