Irodov Problem 1.347

This problem is very similar to Problem 1.346. As seen from the Laboratory reference frame, the Muon's time would be dilated (lowed down) and appear longer. Let the proper decay time of the Muon be . In its own reference frame the Muon will decay in time , however as seen in the Laboratory it will decay in a longer time given by. The distance l traveled by the Muon in the Laboratory reference frame is given by,








b) The distances in the Muon's reference frame will seem to be shrunk as compared to Laboratory and so it will feel it has traveled a much shorter distance given by .
