Question

Determine the angular velocity, in radians per second, of 16.2 revolutions in 7 seconds. π=3.14

Answer 1

To answer the question above, convert the given measurement of the angle in revolutions. The conversion factor is 1 revolution is equal to 2π or 6.28 radians.
(16.2 rev) x (6.28 rad / 1 rev) = 101.736 rad
Then, divide the value obtained with time which is 7. The answer is approximately 14.53 rad/s.
