# Suppose a rocket ship in deep space moves

Suppose a rocket ship in deep space moves with constant acceleration equal to $9.8 m/s^2$, which gives the illusion of normal gravity during the flight. (a) If it starts from rest, how long will it take to acquire a speed one-tenth that of light, which travels at $3.0\times 10^8 m/s?$ (b) How far will it travel in so doing?
