Time Dilation

  1. Aug 10, 2007 #1
    A particle lives for a short time before breaking apart into other particles. Suppose it is moving at a speed of 0.996c, and an observer who is stationary in a laboratory measures the particle's lifetime to be 3.00 10-8 s.
    What is the lifetime according to a hypothetical person who is riding along with the particle?




    3. The attempt at a solution
    I tried
    t=t(0)/(1-v2/c2)^1/2
    where t=3.00 10-8s and i'm finding t(0) proper.
    my answer is 3 10-9 which is wrong. what am I doing wrong?

    I suggest carrying more significant figures in your answer.
