Friction in an old clock causes it to lose 5.6 minutes per hour. Assume the angular acceleration is constant, the positive z axis points out of the face of the clock, and at the beginning of the hour it was at its ideal angular speed. Find the angular acceleration of the minute hand (long hand) and its angular velocity at the end of the hour. (Give your answer for the angular velocity to at least three significant figures. Express your...
