2) You are designing the new galactic Republic space Force defense battleship for protecting against the Sith empire attacks. It launches, using a magnetic rail gun, one kg iron slugs at 0.9c, 0.99c and 0.999c. The battleship weighs 45 million kg. a) How much relativistic energy and relativistic kinetic energy does the iron slug have at each of its launch energies. Give your answer in both GeV and Joules. b) Using the concept of conservation of relativistic momentum what velocity is the battleship moving with after it fires each velocity of slug if the ship is initially stationary in each case. c) Would it be a good idea for Sith warrior to use her command of the Force to slow the slugs to a stop before they hit her ship? Assume with dark side Force powers cannot violate special relativistic and conservation of momentum principles
