The US Army's MH-47E Chinook helicopter is used as a heavy lift vehicle. The rotor has three blades that rotate with a frequency f of 225 revolutions per minute. What is the angular velocity ω of the blades, measured in radians per second?

Explanation:

Given that, the rotor has three blades that rotate with a frequency f of 225 revolutions per minute. We need to find the angular velocity of the blade in radian per second.

Since,

So, the angular velocity becomes :

Hence, this is the required solution.
