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?
