(15%) Problem 8: Suppose a cosmic ray colliding with a nucleus in the Earth's upper atmosphere produces a muon that has speed v = 0.92c. The muon then travels at constant speed and lives 1.5 us as measured in the muon's frame of reference. (You can imagine this as the muon's internal clock.) Randomized Variables y = 0.92 c t = 1.5 us > * 33% Part (a) How long does the muon live in seconds) as observed on the...
