1. Take the mass of a proton to be 1GeV (=1000MeV). Find the velocity (beta) of a proton whose kinetic energy is:
100 MeV2 GeV10 GeV100 GeV
2. According to Newtonian theory, the kinetic energy (mv^2/2) of a particle is c is equal to mc^2/2, which we now recognize as half of its rest energy. What is the actual (relativistic) velocity of a particle whose kinetic energy is equal to half its rest energy?
