How much kinetic energy is in electron volts?
Kinetic energy = 1/2 mv2
1 electron volt = 1.6 x 10-19 J
The Attempt at a Solution
It's a bit unclear to me what the question is asking, since no context at all is given. It's one of the questions in the homework and it's a separate question from the others so it's not part of a bigger problem.
Since kinetic energy is in joules and there is 1.6 x 10-19 Joules in one electron volt, I just put that as the answer, but I feel like I'm missing something? Maybe they're just trying to make us look up the value of an electron volt?
