What is the rotational kinetic energy of the earth? Assume theearth is a uniform sphere. Data for the Earth can be found inthe back cover of the book.
The only data I can find is:
Mass of Earth: 5.98*10^24 kg
Mean radius: 6.37*10^6 m
I know that Krot = .5 I(ω^2)
I'm guessing that I = mass of earth * mean radius^2
since those are average values.
ω = 2π rad/day ????
