16. (Rotation) In figure, two 6.2 kg blocks are commected by a massless string over a pulley of radius 2.40 cm and rotational inertia 7.40 x 10-4 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 axis is frictionless. When this system is released from rest, the pulley turns through 0.650 rad in 91.0 ms and the acceleration of the block is constant. What are i the magnitude of the pulley's angular ac- T R, I celeration, M ii the magnitude of either block's acceler- T ation, M iii string tension T1, iv string tension T2? Answer: i) 159.0 rad/s ii) 3.8 m/s? iii) T = 37.2 N iv) T2 = 32.2 N 16.
