An interstellar ship has a mass of 1.20 * 106 kg and is initially atrest relative to a star system. (a) What constant acceleration is neededto bring the ship up to a speed of 0.10c (where c is the speed of light,3.0 *108 m/s) relative to the star system in 3.0 days? (b) What is that acceleration in g units? (c) What force is required for the acceleration?(d) If the engines are shut down when 0.10c is reached (thespeed then remains constant), how long does the ship take (start tofinish) to journey 5.0 light-months, the distance that light travels in5.0 months?

Question
An interstellar ship has a mass of 1.20 * 106 kg and is initially at
rest relative to a star system. (a) What constant acceleration is needed
to bring the ship up to a speed of 0.10c (where c is the
3.0 *108 m/s) relative to the star system in 3.0 days? (b) What is that acceleration in g units? (c) What force is required for the acceleration?
(d) If the engines are shut down when 0.10c is reached (the
speed then remains constant), how long does the ship take (start to
finish) to journey 5.0 light-months, the distance that light travels in
5.0 months?
