A body is whirled in a horizontal circle at the rate of 800 revolutions per minute. Determine the angular velocity
A
100\(\pi\)rads\(^{-1}\)
B
33.3\(\pi\)rads\(^{-1}\)
C
29.5\(\pi\)rads\(^{-1}\)
D
26.7\(\pi\)rads\(^{-1}\)
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
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
