A block (mass = 1.5 kg) is hanging from a massless cord that is wrapped around a pulley (moment of inertia = 1.3 x 10³ 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 bloc 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 0.037 m during the block's descent. Find (a) the angular acceleration of the pulley and (b) the tension in the cord

Transcribed Image Text:A block (mass = 1.5 kg) is hanging from a massless cord that is wrapped around a pulley (moment of inertia = 1.3 x 103 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 0.037 m during the block's descent. Find (a) the angular acceleration of the pulley and (b) the tension in the cord.
