Chapter 26, Problem 23P

(a)

To determine

The time that an explorer takes to reach to a planet Alpha Centauri from the Earth with respect to an Earth observer, if the explorer travels at a speed of $2.9\times {10}^8\text{ m/s}$ and the distance of Alpha Centauri from Earth is $4.3\text{ light-years}$.

(b)

To determine

The time that an explorer takes to reach to a planet Alpha Centauri from the Earth, with respect to the spaceship, if the explorer travels at a speed of $2.9\times {10}^8\text{ m/s}$ and the distance of Alpha Centauri from Earth is $4.3\text{ light-years}$.

(c)

To determine

The space-time figure for the explorer on Earth and the explorer on spaceship, if the explorer travels at a speed of $2.9\times {10}^8\text{ m/s}$ and the distance of Alpha Centauri from Earth is $4.3\text{ light-years}$.
