The average lifetime of muons at rest is 2.20 μs. A laboratory measurement on muons traveling in a beam emerging from a particle accelerator yields an average muon lifetime of 19.932 μs.
a) What is the speed of the muons in the laboratory? ((I know the answer to this is 2.98e8 m/s))
b) What is their kinetic energy?
c) What is their momentum? (MeV/c - Do not enter a unit) The mass of a muon is 207 times that of an electron.
