Consider an interstellar spaceship powered by matter-antimatter reactions. The energy resulting from the matter-antimatter reactions is ejected from the exhaust as electromagnetic radiation producing thrust. The design goal is to have the thrust produce an acceleration equal to the acceleration of gravity at the earth's surface, g, so the astronauts will experience the effect of normal gravity as they travel. If the spaceship has an initial mass (including fuel) of 40.0 Mg (1000 kg), what is the magnitude of the rate of matter-antimatter burning (in kg/s) to produce the desired acceleration?
