A space craft flying in a straight course with a velocity of 75 km `s^(-1)` fires its rocket motors for 6.0 s. At the end of this time, its speed is 120 km `s^(-1)` in the same direction. Find : (i) the space craft's average acceleration while the motors were firing, (ii) the distance travelled by the space craft in the first 10 s after the rocket motors were started, the motors having been in action for only 6-0 s.
