Homework Statement
How much work must be done to increase the speed of an electron from rest to 0.52c?
Homework Equations
I don't know :)
The Attempt at a Solution
I tried E=Ymc^2 where Y = 1/[1-(v/c)^2]^1/2 and got 3.19821x10^-22 J which translates to 1.998x10^-9 MeV, but I don't think this answer is right. Could someone explain this one to me? Thanks!
