Question
In figure, two 7.30 kg blocks are connected by a massless string over a pulley of radius 1.80 cm and rotational
inertia 7.80 x 10-4 kg.m2. 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 0.560 rad in 89.0 ms and the acceleration of the block is constant. What is the
magnitude of the pulley's angular acceleration? (Your result must be in units of rad /s2 and include 1 digit after
the decimal point. Maximum of 2% of error is accepted in your answer.)
