Ask Custom Question

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?
