Final Speed of an Electron with 22kv Potential Difference?

[SCorneliusJ]

Homework Statement

Assuming the electron starts from rest, what will be the final speed reached by the electron?

We have p.d. of 22kv, and the 'work done on the electron', worked out previously as 3.25^-15

Homework Equations

*shrug* I swear we have never covered this before

The Attempt at a Solution

No idea how to even begin

The work done by the p.d.=Change in kinetic energy of the electron

Work done = p.d. x Charge of the electron

*facepalm* I should have known that.

Thanks rock.freak!
