The fictional starship Enterprise obtains power by combining matter and antimatter, achieving complete conversion of mass into energy. If the mass of Enterprise is approximately 5 X 109 kg, how much mass must be converted into kinetic energy to accelerate it from rest to one tenth the speed of light?
of course, E=mc2 but I don't have the energy so I can't solve for m? What other ways can I approach this problem
the answer in the back of the book is 2.5 X 107 kg
