A particle known as a pion lives for a short time before breaking apart into other particles. Suppose it is moving at a speed of 0.974c, and an observer who is stationary in a laboratory measures the particle's lifetime to be 4.50 multiply.gif 10-8 s.
(a) What is the lifetime according to a hypothetical person who is riding along with the pion?
(b) According to this hypothetical person, how far does the laboratory move before the pion breaks apart?
