Answer:
0.399 rev/s
Explanation:
Given that,
The diameter of a tornado, d = 74 m
Radius, r = 37 m
Linear velocity, v = 335 km/h = 93.05 m/s
We need to find the angular velocity in revolutions per second. Let it is [tex]\omega[/tex]. The relation between angular velocity and linear velocity is as follows :
[tex]v=r\omega\\\\\omega=\dfrac{v}{r}\\\\\omega=\dfrac{93.0556}{37}\\\\\omega=2.51\ rad/s[/tex]
or
[tex]\omega=\dfrac{2.51}{2\pi}\\\\\omega=0.399\ rev/s[/tex]
So, the angular velocity of the blade is 0.399 rev/s.
