At its peak, a tornado is 73.0 m in diameter and carries 395-km/h winds. What is its angular velocity in revolutions per second

Respuesta :

Answer:

The angular velocity of the tornado at its peak is 0.478 revolutions per second.

Explanation:

Let consider that tornado rotates at constant speed. From Rotation Physics we get the following relationship between linear ([tex]v[/tex]) and angular speeds ([tex]\omega[/tex]), measured in meter per second and radians per second, respectively.

[tex]\omega = \frac{v}{R}[/tex] (Eq. 1)

Where [tex]R[/tex] is the radius of the tornado, measured in meters.

If we know that [tex]v = 109.722\,\frac{m}{s}[/tex] and [tex]R = 36.5\,m[/tex], then the angular speed of the tornado at its peak is:

[tex]\omega = \frac{109.722\,\frac{m}{s} }{36.5\,m}[/tex]

[tex]\omega = 3.006\,\frac{rad}{s}[/tex] [tex]\left(0.478\,\frac{rev}{s} \right)[/tex]

The angular velocity of the tornado at its peak is 0.478 revolutions per second.
