In the figure below, block 1 has mass m1 = 440 g, block 2 has mass m2 = 512 g, and the pulley, which is mounted on a horizontal axle with negligible friction, has radius R = 5.50 cm. When released from rest, block 2 falls 70.9 cm in 5.23 s without the cord slipping on the pulley. What is its rotational inertia of the pulley? Specify your answer in SI units up to 4 decimal places. Do not include units.
