What is the velocity of a muon at the surface

Reference no: EM13244700

A) A muon is produced by a collision between a cosmic ray and an oxygen nucleus in the upper atmosphere at an altitude of 50 km. It travels vertically downward to the surface of the Earth where it arrives with a total energy of 180 MeV. The rest energy of a muon is 105.7 MeV. What is the kinetic energy of a muon at the surface?

B) What is the velocity of a muon at the surface? (Give your answer as a fraction of the speed of light c.)

C) What is its momentum at the surface? (Give your answer in units of MeV/ c. There is no need to enter units.)
