My first question I want to know the amount of energy in a moving mass. Using the equation E=MC^2/sqrt(1-(V^2/C^2)) (Which is the full form of E=mc^2 i think) i should be able to find out the amount of energy there is of a mass plus its movement altogether. So say a person sees a 1kg object moving an .9c in a straight line in space. Now doing the calculation out - 1*C^2/sqrt(1-((.9*C)^2/C^2) which = 2.064741605e17 joules. Is this the correct answer?? Once this is answered i will ask my second question.
