Question:

In 1998, NASA launched Deep Space 1 (DS-1), a spacecraft that successfully flew by the asteroid named 1992 KD (which orbits the sun millions of miles from the earth). The propulsion system of DS-1 worked by ejecting high-speed argon ions out the rear of the engine. The engine slowly increased the velocity of DS-1 by about 19.0 m/s per day.
(a) How much time (in days) would it take to increase the velocity of DS-1 by 12700 m/s?
(b) What was the acceleration of DS-1 (in m/s2)?
