Length Contraction

  1. Sep 24, 2006 #1
    A star is measured to be 40.0 ly from Earth, in the inertial frame in which both star and Earth are at rest.

    A) what would you determine this distance to be if you travveled to teh star in a space ship moving at 1.0x10^8 m/s relative to earth.

    answer is 37.7 ly (calculated that, with no problem)

    b) How long would you determne the journey to take?

    ok this is where i get stumpped

    I converted ly to m and got some result.
    do u convert this distance to time using v=d/t

    if you do that what do you after?

    where do i go from here?
