How do you find the maximum kinetic energy of a single electron when you only know the mass and velocity of the ejected electron as well as the frequency of the incident light? How the do you find the energy required to eject the electrons with only this information?

Since the velocity of the ejected electon can vary between zero to a maximum value,with the given information alone one cannot find the maximum kinetic energy.

Aditional information such as the stopping potnetial or the threshold frequency must be known.
