A FLYWHEEL WITH A MOMENT OF INERTIA 6.00 * 10^6 kg*m^2 is spinning with an angular speed of 120 rev/s about a vertical axis while it sits at the north pole. The disk is turning counterclockwise when viewed from above. The disk is brought to rest. Treat the earth as a uniform sphere with a mass 5.976 * 10^24 and a radius 6.374 *10^6 m.
A. What will be the magnitude of the change in angular momentum on earth?
B. What will be the change in length of a day on earth?
