Find the speed in both radians per second and degrees per second for the hour
hand, the minute hand, and the second hand on a clock.

  • Trig -

    1 hours = 60 minutes = 3600 seconds

    I will do one of them for you, you try the others

    angular speed of hour hand:
    = 1 rotation/ per 12 hrs
    = 2π radians/12(3600) seconds
    = (π/21600) radians/second

    or
    = 360° degrees /12 hrs
    = (360/12(3600)° / second
    = 1/120 degrees/second
