Initially, a person is sitting stationary on stool that can rotate on a frictionless pivot; and the person is holding spinning wheel with its axis vertical as shown: The moment-of-inertia of the person +stool about the stool's axis is Ip = 20 kg m? The wheel has moment-of-inertia Iw = 5 kg m? about it axis and it is initially spinning with fw = 3 rev/s, oriented so its angular momentum vector Lw is pointing down: The person then carefully flips the axle of the wheel so that it is still rotating with fw = 3 rev/s (relative to the room), but it is nOW oriented so its angular momentum vector Lw is pointing up. What is the final rotation rate of the person? Iw = 5 kg m fw = 3 revls fw = 3 revls Ip = 20 kg m? =0 fp = ? Initial Final zero B) 1 revls revls D) revls E) 2 revls
