Relative Acceleration Across a Potential Difference

[Paulman35]

Electrons are accelerated from rest through a potential difference of 277000 .

a) What is the final speed predicted classically? in m/s

b) What is the final speed predicted relativistically? in m/s

Can you show what you've tried so far to get to the solution?

 

[Paulman35]

I don't even know where to start.

What is the energy gained by the electron?

 

[Paulman35]

This is all of the information I have, If I knew any other information I would have included it in the question.
