A body is whirled in a horizontal circle at the rate of 800 revolutions per minute. Determine the angular velocity
The correct answer is: D
Explanation
Angular velocity(\(\omega\)) = 2\(\pi\) x rev per sec
Rev. per sec = \(\frac{800}{60}\) \(\approxeq\) 13.33 rev/s
Angular velocity(\(\omega\)) = 2\(\pi\) x 13.33 \(\approxeq\) 26.7\(\pi\)rad/s
