Special Relativity: space ship

  1. Dec 6, 2008 #1
    1. The problem statement, all variables and given/known data
    In the far future, a spaceship is traveling from Earth to Saturn at 0.1c when it receives a terrorist threat. The crew learns that a bomb will go off in 3 hours. To prolong this time, the captain accelerates the ship to 0.7c. How long do they have to find the bomb now?

    2. Relevant equations
    [tex]\Delta[/tex]t'=[tex]\gamma[/tex][tex]\Delta[/tex]t


    3. The attempt at a solution
    By manipulating the equation, I solved for [tex]\Delta[/tex]t'
    3/[tex]\sqrt{1-(0.7)^2}[/tex]= 4.2 hours

    Where did I go wrong? Was the Lorentz transform done correctly?

    Is the bomb and its timer on board the ship? Does increasing your speed change the rate at which your clock runs as far as you are concerned?
