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 0.992c, and an observer who is stationary in a laboratory measures the particle's lifetime to be 5.00 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 lab move before the pion breaks apart?
