Physics

Muons are unstable subatomic particles with a mean lifetime of2.2 Î¼s that decay to electrons. They are produced when cosmic raysbombard the upper atmosphere about 10 km above the earthâ€™s surface,and they travel very close to the speed of light. The problem wewant to address is why we see any of them at the earthâ€™ssurface.What is the greatest distance a muon could travel duringits 2.2 Î¼s lifetime?According to your answer in part A, it wouldseem that muons could never make it to the ground. But the 2.2 Î¼slifetime is measured in the frame of the muon, and they are movingvery fast. At a speed of 0.999c, what is the mean lifetime of amuon as measured by an observer at rest on the earth?
