Question

The angular speed of the minute hand of a wrist watch in radius/s is....

Answer 1

Angular speed (w) = theta/time

For minute hand T = 60 min = 60× 60 = 3600 sec

and it cover 2π distance

w = 2π/ 3600

w = 2× 3.14/ 3600

w = 6.28 / 3600

w = 1.74 × 10^ -3 radian /sec

Hope so it helped you dear friend
