Comfortable acceleration assumes that a rocket ship in deep, Ask an Expert

Academics

Comfortable Acceleration assumes that a rocket ship in deep space moves with the constant acceleration equivalent to 9.8 m/s², which gives the illusion of the normal gravity throughout the flight.

Q1. If it begins from rest, how long will it take to obtain a speed of 0.23 times that of light, which travels at 3.0 x 10⁸ m/s?

Q2. How far will it travel in doing so?

Q3. How long will it take to get a speed 0.15 times that of light? How far will it travel in doing so?
