Time dilation equation help

  1. Jan 29, 2006 #1
    I have the attached equation
    but when I plug it, I dont get the same answer as in the back of the book...

    Here is the question

    Two observers, A on earth, B in a spacecraft whose speed is 2.0X10^8 m/s both set their watches to the same time, when the ship is abreast the earth.

    How much time must elapse by A's reckoning before the watches differ by 1.00 seconds?

    What did you plug in? We can't help you if we don't know what you've tried to do.

    Hint: which one is bigger, [itex]T_0[/itex] or [itex]T_1[/itex]?

    After approx 5.449 secs of Earth time, the spaceship will be 1 sec. behind.
    In your thumbnail, Earth time should be on the left of the equation.
