Question

The angular velocity of the second hand of a clock is dash?

Answer 1

angular velocity of the seconds hand of a clock is 2pi radians

Answer 2

angular displacement divided by time taken is the angular velocity

now displacement is 2pi r  and the time taken is 60sec so thet

(it depends on  the radius of the clock ) another way

= 2pi r/60
=pi r/30 rad/sec
