2 m (a) What is the lifetime according to ahypothetical person who is riding along with the pion? 1 s (b) According to this hypothetical person, how far does thelaboratory move before the pion breaks apart? 2 m A particle known as a pion lives for a short time before breakingapart into other particles. Suppose it is moving at a speed of0.980c, and an observer whois stationary in a laboratory measures the particle's lifetime tobe 5.00
Explanation / Answer
v = 0.980 c, t = 5.00*10-8 s a) t0 = t(1 - v2/c2) =9.95*10-9 s b) vt0 = 2.93 m
