Earth rotates once on its axis every 24 hours. (a) What is the angular velocity of Earth? (b) Given that Earth has a radius of 6.4 x 106 m at its equator, what would be the tangential velocity of someone standing at the equator as measured by a “stationary” observer?
Homework Answers
Given is:-
Time taken by earth to rotate once = 24 hours
Radius of the Earth 
Now,
Part - a
Angular velocity is given by
by plugging all the values we get
which gives us
Part - b
Tangential velocity is given by
plugging the values
which gives us
