1. The problem statement, all variables and given/known data Ive been trying to find the Inertia and Kinetic energy of the sun. I have a feeling im using the wrong formulas to obtain the answer. Mass of sun 2*10^30kg Radius of sun 700*10^6 m t spin = 26 days the answers should be I = 4.0 * 10^98 K energy = 1.5 * 10^16 2. Relevant equations I=(2/5)*M*R^2 K= (1/2)M*(ω^2)*(r^2) ω = 2pi/t 3. The attempt at a solution If someone knows how to do this i would really appreciate it.
