A pulley with a radius of 3.0 cm and a rotational inertiaof4.5Ã10â3 kg ·m2 is suspended from
the ceiling. A rope passes over it with a 2.0-kg block attachedtoone end and a 4.0-kg block
attached to the other. The rope does not slip on the pulley.Whenthe 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
