It takes 23 hours 56 minutes and 4 seconds for the earth to make one revolution (mean sidereal day). What is the angular speed of the earth

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

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.

i think they are all correct

explanation:

they seem good

it is called kinetic energy
