Rotational rigid body 4

Example:
A 5.00 kg object placed on a frictionless horizontal table is connected to a string that passes over a pulley and then is fastened to a hanging 9.00 kg object. The pulley has a radius of 0.250 m and moment of inertia I. The block on the table is moving with a constant acceleration of 2.00 m s-2.
(a)    Sketch free body diagrams of both objects and pulley.
(b)   Calculate T1 and T2 the tensions in the string.
(c)    Determine I.
