Nuclear-powered rockets were researched for some years before safety concerns became paramount.
(a) What fraction of a rocket's mass would have to be destroyed to get it into a low Earth orbit, neglecting the decrease in gravity? (Assume an orbital altitude of 250 km, and calculate both the kinetic energy (classical) and the gravitational potential energy needed.)
(b) If the ship has a mass of 1.00 x 105 kg (100 tons), what total yield nuclear explosion in tons of TNT is needed?
