A particle known as a pion lives for a short time before breaking apart into other particles. Suppose a pion is moving at a speed of 0.990c, and an observer who is stationary in a laboratory measures the pion’s lifetime to be 3.5 x 10^8s. (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?

Question
A particle known as a pion lives for a short time before breaking apart into other particles. Suppose a pion is
moving at a speed of 0.990c, and an observer who is stationary in a laboratory measures the pion’s lifetime to
be 3.5 x 10^8s. (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?
