I'm trying to solve E=mc2, I'm not sure if I'm doing it correctly though, so I'll model out what I'm doing.
First, the mass of the object 5 kg.
So you plug in the numbers E=(5)(299 792 458 m / s), and then, you just multiply and you get 1,498,962,290 joules, and that's the amount of energy you need to move an object that weighs 5kg (11 lbs) at the speed of light.
Is that correct?
edit: Unfortunatly I forgot to square the speed of light, so the amount of energy from the annihilation of a 5 kg (11 lb) object would be 2.246887947x1018
