Pulley with rotational Inertia

In the figure which is shown at ‘click here’ two 6.20 kg blocks are connected by a massless string over a pulley of radius 2.40 cm and rotational inertia 7.40 x 10^-4 kg m^2 . the string does not slip on the pulley , it is not known whether there is friction between the table and the sliding block; the pulleys axis is frictionless. When this system is released from rest , the pulley turns through 1.30 rad in 91.0 ms and the acceleration of the block is constant . What are

a) the magnitude of the pulley’s angular acceleration

b) the magnitude of either blocks acceleration

c) string tension T1

d) string tension T2
