Problem 4: Suppose a cosmic ray colliding with a nucleus in the Earth's upper atmosphere produces a muon that has speed v=0.74c. The moon then travels at constant speed and lives 1.6 us as measured in the moon's frame of reference. (You can imagine this as the muon's internal clock.) Randomized Variables v=0,74 c r = 1.6 µus Lo Part (a) How many kilometers does the muon travel according to an Earth-bound observer?
