The "muon" - a subatomic particle denoted with the Greek letter u - has a rest mass of m. = 1.06x10° eV/c². A ground-based observatory measures the total energy of a muon formed in the Earth's atmosphere to be E = 2.5×10° eV. a) Calculate the Lorentz factor y for the muon. Is it relativistic? b) Calculate the kinetic energy Ek of the muon in eV and in Joules.
