An object of mass m1 = 4.50 kg is connected by a light cord to an object of mass

An object of mass m1 = 4.50 kg is connected by a light cord to an object of mass m2 = 3.00 kg on a frictionless surface (see figure). The pulley rotates about a frictionless axle and has a moment of inertia of 0.570 kg · m² and a radius of 0.310 m. Assume that the cord does not slip on the pulley. 

(a) Find the acceleration of the two masses. m/s2 

(b) Find the tensions T1 and T2
