i have a question where i am given the fermi energy and work function of a samplen, i need the velocity of an escaping electron, am i correct in saying i can use the following formula?

h-bar.w = kinetic + work function

were i substitute the fermi energy for the kinetic energy? therefore finding w and then velocity...

it seems like such a trivial question but i cant seem to convince myself that is correct.
