Question

the angular accelaration of second hand of a watch is?​

Answer 1

Answer:

The Physics

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

Answer:

The average angular acceleration of the second hand is zero
