Expert Answer:

The hour hand goes through one complete revolution in 12 hrs.

i.e. 2π in 12 hrs = 2x3.14/(12x3600) = 1.45 x 10 -4 rad/s

Similarly the minute hand goes through one complete revolution in 1 hr,

so it's angular velocity is, = 2x3.14/(3600) = 0.0017 rad/s

Similarly for the second hand = 2x3.14/60 = 0.104 rad/s.
