A pion is an unstable particle that has a mean lifetime of 2.55 x 10^-8 s. Thi si the time interval between its creation in a nuclear process and its extinction into decay products, as measured in a frame of reference at rest with respect to the pion. An average pion is traveling at 0.230 c relative to Earth. How far does it travel in its lifetime, relative to Earth?

Muons are unstable subatomic particles that decay to electrons with a mean lifetime of 2.2 μs . They are produced when cosmic rays bombard the upper atmosphere about 12.4 km above the earth's surface, and they travel very close to the speed of light. The problem we want to address is why we see any of them at the earth's surface. a) What is the greatest distance a muon could travel during its 2.2 μs lifetime? b) According to your...
