In the figure, two 7.10 kg blocks are connected by a massless string over a pulley of radius 2.00 cm and rotational inertia 7.40 x 10 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 0.700 rad in 143 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 T, and (d) string tension T,? Assume free-fall acceleration to be equal to 9.81 m/s?. (a) Number Units (b) Number Units (c) Number Units (d) Number Units
