Solve the following questions given below:
Question I: According to Newtonian physics (kinetic energy = 1/2mv2), how much work (keV) is 2 required to accelerate an electron from rest to 1.74 c?
Question II: If we do that much work on an electron, what will its final speed actually be? Give the speed in terms of c.
I don't just need an answer, work and explanations/walkthrough would be much appreciated! Thanks.
