Question

In a demonstration, a bicycle wheel with moment of inertia 0.37 kg.m2 is spun up to 14 rad/s, rotating about a vertical axis. A student holds the wheel while sitting on a rotatable stool. The student and the stool are initially stationary and have a moment of inertia equal to l 3.60 kg.m2. If the student turns the bicycle wheel over so its axis point in the opposite direction, with what angular velocity will the student and stool rotate? Assume the wheel, student, and stool all have the same axis of rotation.
