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.

dang that balls went far

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
