A lady is on a lab chair. The chair can freely spin on its axis (no friction). The lady was given an initial spin. While she is spinning freely, she extends her arms out O her moment of inertia increases and her angular speed decreases her moment of inertia increases and her angular speed increases. O her moment of inertia decreases and her angular speed increases O her moment of inertia increases and her angular speed remains the same. O her moment of inertia decreases and her angular speed decreases.
