Suppose a cosmic ray colliding with a nucleus in the Earth's upper atmosphere produces a muon that has speed v= 0.83c. 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 v=0.83c t=1.5 us (a) How long does the muon live in seconds) as observed on the Earth? b) How many meters does it travel as observed on the Earth?...

Suppose a muon produced as a result of a cosmic ray colliding with a nucleus in the upper atmosphere has a velocity v = 0.950c. Suppose it travels at constant velocity and lives 2.20 ps as measured by an observer who moves with it (this is the time on the muon's internal clock). It can be shown that it lives for 4.87 us as measured by an Earth-bound observer. (a) How long (in us) would the muon have lived as...
