A pulley with a radius of 3. 0 cm and a rotational inertia of 4. 5×10-3 kg·m2 is suspended from the ceiling. A rope passes over it with a 2. 0-kg block attached to one end and a 4. 0-kg block attached to the other. The rope does not slip on the pulley. When the speed of the heavier block is 2. 0 m/s the kinetic energy of the pulley is:.
