Question: A xenon ion engine with Isp = 9 5 0 0 sec is to be used to accelerate a spacecraft to a velocity of 0

A xenon ion engine with Isp =9500sec is to be used to accelerate a spacecraft to a velocity of 0.01 percent the speed of light (CSL), i.e., V =0.0001CSL. If the empty (dry) mass of the spacecraft is 12 kg, how much xenon is required? What assumptions did you make? Discuss the validity of these assumptions for this mission.
