Question

The angular speed of the second hand of a watch is:
A) (  $\pi$ /1800) rad/s
B) (  $\pi$ /60) m/s
C) (  $\pi$ /30) m/s
D) (2  $\pi$ ) m/s
E) (60) m/s

Quizplus · Accepted Answer

The second hand completes one revolution in 60 seconds (1 minute). Therefore, its angular speed in radians per second is given by:
angular speed = (2π radians) / (60 seconds)
angular speed = π / 30 radians per second
Thus, the correct answer is C.

The Angular Speed of the Second Hand of a Watch π\piπ

The Angular Speed of the Second Hand of a Watch $\pi$
