What is the speed of the muons in the beam

Reference no: EM13648791

The muon's rest mass is 105.7 MeV/c2, and itslife-time is 2.2 x 10-6 s. Consider a beam of muons with a kineticenergy of 800 MeV. What is its life-time in the beam observed in the laboratory frame ? What is the speed of the muons in the beam?
