A particle lives for a short time before breaking apart into other particles. Assume it is moving at a speed of 0.976c, and an observer who is stationary in a laboratory measures the particle's lifetime to be 5.00 *10-8 s.
1. What is the lifetime according to a hypothetical person who is riding along by the particle?
2. According to this hypothetical person, how far does the laboratory move before the particle breaks apart?
