The initial angular velocity of the star will be [tex]w=2.4\times 10^{-6} \ \frac{rad}{sec}[/tex].

What is angular velocity?

Angular velocity refers to how fast an object rotates or revolves relative to another point. It is a rate of change of angle.

Here for the 30 days period the angular velocity will be calculated as:

[tex]W=\dfrac{2\pi}{T}=\dfrac{2\times \pi}{30\times 24\times 3600}=2.4\times 10^{-6} \ \frac{rad}{sec}[/tex]

So the initial angular velocity of the star will be [tex]2.4\times 10^{-6} \frac{rad}{sec}[/tex]
