An electron and a positron (an anti electron) make a head-on collision, each moving at v = 0.99999c. In the collision the electrons disappear and are replaced by two muons (each muon mc^2 = 105.7 MeV) that move off in opposite directions. What is the kinetic energy (MeV) of each of the muons?© BrainMass Inc. brainmass.com March 4, 2021, 11:36 pm ad1c9bdddf
The total energy of the electron + positron is 2 gamma m c^2 = 228.526 MeV
By energy conservation, this is also the ...
A solution using conservation of energy and momentum is given.
