An accelerator increases the total energy of electrons uniformly to 10 GeV over a 3000 m path. That means that at 30 m. 300 m, and 3000 m, the kinetic energy is 108. 109. and 1010 eV, respectively. At each of these distances, compute the velocity, relative to light (v/c), and the mass in atomic mass units.
