    Finding the relativistic speed of a spacecraft

    Thank you, you are absolutely right. I guess I was just too quick in my head and that is why I thought that sqrt(1/2)=1/4. Now, if 1-beta^2 = beta^2, then 1/2 = beta^2 and beta = 1/sqrt(2) That also sounds much more reasonable. Thanks again!

    Finding the relativistic speed of a spacecraft

    Homework Statement If a spacecraft is traveling to a star which is located at a distance of 1 lightyear and it would take the spacecraft 1 year to reach the star in its own frame, how fast would the spacecraft actually fly? Also, how long would the journey take for an observer on Earth...
