    Answer:


    The angular velocity of Earth is π/12 radians per hour.


    The angular velocity of Earth is 2π radians per day.


    Step-by-step explanation:


    A full circumference of a circle (as the Equator line on Earth) is 2π radians.


    Since the planet does a full revolution in 24 hours… that means it makes a full turn in a day.


    So, we can see that in a day, the planet rotates 360 degrees… or 2π radians per day!


    Now, if you want to find the angular velocity per HOUR… you divide that by 24… so  2π/24 = π/12 radians


    So, we can also say it does π/12 radians per hour.
