A person stands on a platform, initially at rest, that can rotate freely without friction. The moment of inertia of the person plus the platform is IP. The person holds a spinning bicycle wheel with its axis horizontal. The wheel has moment of inertia IW and angular velocity ωW. Take the ωW direction counterclockwise when viewed from above. Part A

What will be the angular velocity ωP of the platform if the person moves the axis of the wheel so that it points vertically upward?Part B

What will be the angular velocity ωP of the platform if the person moves the axis of the wheel so that it points at a 60 ∘ angle to the vertical?Part C

What will be the angular velocity ωP of the platform if the person moves the axis of the wheel so that it points vertically downward?Part D

What will ωP be if the person reaches up and stops the wheel in part A?
