In the figure, two 9.50 kg blocks are connected bya massless string over a pulley of radius 1.80 cm and rotational inertia 7.40 x 104 kg-m?. The string does not slip on the pulley: it is not known whether there is friction between the table and the sliding block; the pulley's axis is frictionless. When this system is released from rest, the pulley turns through 1.10 rad in 127 ms and the acceleration of the blocks is constant. What are (a) the magnitude of the pulley's angular acceleration, (b) the magnitude of either block's acceleration. (c) string tension T1, and (d) string tension T2?

Question
In the figure, two 9.50 kg blocks are connected bya massless string over a pulley of radius 1,80 cm and rotational inertia 7.40x 104
kg-m?. The string does not slip on the pulley: it is not known whether there is friction between the table and the sliding block: the
pulley's axis is frictionless. When this system is released from rest, the pulley turns through 1.10 rad in 127 ms and the acceleration of
the blocks is constant. What are (a) the magnitude of the pulley's angular acceleration, (b) the magnitude of either block's acceleration.
(c) string tension T1, and (d) string tension T2? Assume free-fall acceleration to be equal to 9.81 m/s?.
