Consider a cosmic ray colliding with a nucleus in the Earth's upper atmosphere that produces a muon which has velocity v = 0.916c. The muon then travels at constant velocity and lives 1.52 us as measured in the muon's frame of reference (You can imagine this as the muon's internal clock.) (a) How far (in km) does the muon in travel according to an Earth-bound observer? (b) How far (in km) does it travel as viewed by an observer moving with it? Base your calculation on its velocity relative to th Earth and the time it lives (proper time).
