A block (mass = 2.2 kg) is hanging from a massless cord that is
wrapped around a pulley (moment of inertia = 1.6 x 10-3 kg·m2), as
the figure shows. Initially the pulley is prevented from rotating
and the block is stationary. Then, the pulley is allowed to rotate
as the block falls. The cord does not slip relative to the pulley
as the block falls. Assume that the radius of the cord around the
pulley remains constant at a value of 0.032 m during the block’s
descent. Find (a) the angular acceleration of the pulley and (b)
the tension in the cord.
