Three 20.0-gram masses are 9.4 cm from an axis of rotation and rotating at 152 revolutions per minute. What is the moment of inertia of the three-object system? The strings holding the masses are of negligible mass. Rotational Kinetic Energy is also solved for and correct units are determined. Want Lecture Notes? This is an AP Physics 1 topic.
