Question

Find the exact angular velocity in radians per hour wind W= 4.1 rpm

Answer 1

1545.66 rad/h

Explanation:

We need to find the angular velocity in rad/hour when wind is moving with a speed of 4.1 rpm.

We know that,

1 revolution = 2π rad

1 hour = 60 minute

So,

`4.1\ rmm = 4.1* (2\pi )/(((1)/(60)))\ rad/h\\\\=1545.66\ rad/h`

So, the required angular velocity is 1545.66 rad/h.
