two protons approach each other head on at 0.5c relative to reference frame S0. a) calculate the total kinetic energy of the two protons as seen in frame s0 b) calculate the total kinetic energy of the protons as seen in reference frame S which is moving with speed 0.5c relative to s0 so that one of the protons is at rest
