A pulley with a radius of 3.0 cm and a rotational inertia of4.5×10−3 kg ·m2 is suspended from the ceiling. A rope passes over it with a 2.0-kg block attached toone 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 2.0m/s the kinetic energy of the pulley is:

A. 0.15 J
B. 0.30 J
C. 1.0J
D. 10 J
E. 20 J
