    Just simple question to check
    1. The problem statement, all variables and given/known data
    A muon formed in the high Earth's athmoshere travels at speed v=0.999c
    for a distance of a L=4.6 km before he decays.How long does he live as it measured in his frame?





    3. The attempt at a solution

    [tex]t=\frac{L/\gamma}{v}[/tex]
