The predominant mode of decay for the charged pions is into a muon and a neutrino. The positive pion results in the neutrino and the negative pion in the antineutrino.
(a) Write the decay equations of both charged pions, being sure to indicate the correct muon charge and correct neutrino type.
(b) Assuming a was created with a kinetic energy of 500 MeV, determine its speed.
(c) How far would the average π- travel in the laboratory before decaying?
(c) What is the sum of the muon’s kinetic energy and the neutrino’s energy?
