A block of mass 1.63 kg is hanging from a massless cord that is wrapped around a pulley (moment of inertia = 1.04E-3 kg·m^2). 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, and assume that the radius of the cord remains constant at a value of 0.043 m during the block's descent. Find the angular acceleration of the pulley and the tension in the cord.
