In the figure, two 6.20 kg blocks are connected by a massless string over a pulley of radius 2.40 cm and rotational inertia of 7.40 Times 10^-1 kg m^2. The string does not slip on the pulley; and there is no 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 1.30 rad in 91.0 ms and the acceleration of the blocks is constant. What are...
