Question

Find out the average angular speed and angular speed of the second hand of clock.

Answer 1

The second hand of the clock moves $2\pi$ radian in $60s$.

therefore, the average angular speed of the second hand is,

${\omega }_{av}=\frac{\Delta \theta }{\Delta t}$

$=\frac{2\pi }{60}$

$=0.105rad/s$

As the motion of the second hand is uniform throughout therefore, the angular speed of the second hand will be equal to the average angular speed that is $0.105rad/s$.
