When it is 6:00, the hour hand on an analog clock is 180 ahead of the minute hand. How many minutes elapse (to three significant digits) before the minute hand next points in the same direction as the hour hand?

The long hand on a clock is known as the minute hand. Usually, it completes one clockwise rotation each hour. A particular clock, however, is slowing down at a constant rate of . Choose a coordinate system such that a z-axis points out of the clock.

a. What is the direction of the minute hand's angular acceleration?

b. Suppose the slow clock and a working clock both read noon at the same moment and at that moment their angular velocities are equal. What does the broken clock read when the working clock reads 1 PM?  

Friction in an old clock causes it to lose 1 minute 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.
