    The speed of light observed in the frame S will be c = x. 2 − x. 1 t. 2 − t. 1. = c ... Show that the relativistic expression for the kinetic energy of a particle (Eq. 1.2) reduces to the ... 1 and 2. Assume you can measure accurately the energies and momenta of ... electron–neutrino system as one object with a mass of a few MeV.
