(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

What is the ratio of the rotational kinetic energy of the Earth to the rotational kinetic energy of the Moon as they spin about their axes?

3. The attempt at a solution

Me = Mass of Earth (5.97 × 1024 kg)

Re = Radius of Earth (6.37 × 106 m)

Mm = Mass of Moon (7.35 × 1022 kg)

Rm= Radius of Moon (1.74 × 106 m)

this is all i know I don't know where to start. I know KE=(1/2)(moment of inertia)(angular velocity)
