A particle lives for a short time before breaking apart into otherparticles. Suppose it is moving at a speed of 0.972c, and an observer who is stationaryin a laboratory measures the particle's lifetime to be 5.00 x 10-8 s.
(a) What is the lifetime according to a hypothetical person who is riding along with the particle?
(b) According to this hypothetical person, how far does thelaboratory move before the particle breaks apart?
