Time dialtion

  1. Mar 15, 2009 #1
    1. The problem statement, all variables and given/known data
    A space ship is going at .4 the speed of light, find its y value.


    2. Relevant equations
    i think your suppose to use y=1/[tex]\sqrt{}1-(v/c)^2[/tex]


    3. The attempt at a solution
    I got y=7.64*10^11
    I also see a chart that says at .4 of c the y should only equal abought 1.
    My calculator was also say " Domain Error" I dont know why. Also what exactly does y stand for?

    What units do you measure time dialtion in?

    It's dimensionless. It's a ratio of two times.

    Yes, your answer will be very close to 1. Time dilation doesn't get very large until you get very close to c.

    Why do i keep getting Domain error.

    Can you show us explicitly what you type or key in?

    Never mind I think my calculator was malfunctioning, I just got it to work and got the right answer.
