A turntable (moment of inertia IT) spins freely at ω0. A student standing at the center of the turntable (moment of inertia IS about the vertical axis) holds a spinning bicycle wheel (moment of inertia IW about its axle) with its spin axis vertical, rotating at angular speed Ω relative to the student in the same direction as the turntable. The student flips the wheel so its axle remains vertical but its spin direction relative to the student is reversed. Which expression correctly gives the final angular velocity ωf of the turntable–student system after the flip?
