(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The muon is an elementary particle that decays with a mean (rest) lifetime of 2.20E-6 s. A beam of muons has a speed of 0.600c. In the reference frame of the muon, how far does the laboratory travel in one mean lifetime?

2. Relevant equations

[tex]L=\frac{L_o}{\gamma}[/tex]

3. The attempt at a solution

a. The muon has to travel (2.20E-6 s)(.60c)=396m seen from the muon

so isn't it [tex]L=\frac{L_o}{\gamma}[/tex] where [tex] \gamma=1.25[/tex]

that would equall 316.8 m to the muon

b. 396 m
