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

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 () and angular speeds (), measured in meter per second and radians per second, respectively.

(Eq. 1)

Where is the radius of the tornado, measured in meters.

If we know that and , then the angular speed of the tornado at its peak is:

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

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

true tan speed = ang vel x radius
