1. (77 pts) A group of pions is observed traveling at speed 0.9c in a particle physics accelerator. The proper half-life of the pions is 1.8x10-s. A) What is the half-life according to the pions? B) What is the half-life according to the scientist standing in the lab? C) Does the pion or the scientist see the proper distance traveled? D) What is the average distance traveled according to the scientist? E) What fraction of a lightyear is the distance calculated in part D?
