Answer:
The angular speed of the Earth is approximately
radians per second.
Step-by-step explanation:
We suppose that Earth rotates at constant angular speed. From Rigid Body Physics, we remember that angular speed of the planet (
), measured in radians per second, is:
(Eq. 1)
Where
is the period, measured in seconds.
Therefore, the angular speed of the planet is:


The angular speed of the Earth is approximately
radians per second.
