Question

The angular speed of minute arm in a watch is?

Answer 1

The angular velocity is independent of the clock size, however for larger clocks the linear velocity of the pointers at the end of the hands will be greater. The second hand goes through 2π radians in 1 min, or 2π radian/60 seconds, so ω = π/30 rad.s-1 = 0.03 rad.s-1

Answer 2

The angular speed of a minute hand is 250 milisecond
