Homework Statement
My question is obscure, but i had to ask. :smile:
Lets say i built a ship that could hold the crab nebula(dimensions of the ship 15km*15km*20km).
Now I want to use the nebula to power my ship somewhat like a flywheel. I would like to hear some possible solutions...
Thanks for answering the question, I now see what i did wrong. The I = 4.0 * 10^98 was a note taking error, lol just a slight difference from the real answer.
Homework Statement
Ive been trying to find the Inertia and Kinetic energy of the sun. I have a feeling I am 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
