Question

A stone moving along a circular path makes 20 revolution in 10 sec. The angular velocity of Stone is -------- rad/s .

Answer 1

Answer:

12.57 rad/sec

Explanation:

As we know, frequency = Number of revolution per second = 2 sec^-1

Then, angular velocity of the stone = 2*pi*f = 2*pi*2 = 12.57 rad/sec
