You are sitting on a chair that is free to rotate (without friction) about a vertical axis passing through its center. One of your friends spins the chair (and you) clockwise (as viewed from above) and, at the same time, another friend hands you a flywheel that also rotates clockwise (as viewed from above). You then flip the flywheel upside down so that it is now rotating counterclockwise (as viewed from above). Briefly explain what will happen to the chair's (and your) motion, in terms of the speed and direction of the rotation, immediately after you flip the flywheel.
