SUMMARY
An electron traveling at 0.422c requires calculations for relativistic momentum, kinetic energy, rest mass energy, and total energy. The relativistic momentum is calculated using the formula p = Ɣmu, where Ɣ is the Lorentz factor. The attempt at a solution indicates that the momentum is approximately 0.551 kg·m/s, using the rest mass of the electron for accurate results. Further calculations for kinetic energy, rest mass energy, and total energy are necessary to complete the problem.
