A uniform thin rod with length L and mass m is placed flat on a horizontal table with friction coefficient M. suppose that the rod rotates around the center o with angular velocity W at the beginning and perpendicular to the axis of the table. Try to find (1) the friction torque used on the rod. (2) how long does it take for the rod to stop rotating

Friction torque: 1 / 4umgl
Time: 1 / 3 * WL / (UG)
