A storm 10.0 km in diameter has wind speeds of 10.0 m/s. What is its angular velocity in radians per second

Aloiza [94]

Answer:

The value is $w= 2*10^{-3} \ rad/s$

Explanation:

From the question we are told that

The diameter of the storm is $d = 10.0 \ km = 10 000 \ m$

The wind speed is $v = 10.0 \ m/s$

Generally the radius is mathematically represented as

$r = \frac{d}{2}$

=> $r = \frac{10000}{2}$

=> $r = 5000 \ m$

Generally the angular velocity is mathematically represented as

$w= \frac{v}{r}$

=> $w= \frac{10}{5000}$

=> $w= 2*10^{-3} \ rad/s$
