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 velocity of the heavier block is 2.0 m/s the total kinetic energy of the pulley and blocks is:


A) 2.0 J
B) 12 J
C) 14 J
D) 22 J
E) 28 J
