What is the velocity of an electron ejected by a photon with a wavelength of 45.0 nm from a metal surface with a binding energy of 4.00 eV (1 eV = 1.602 x 10-19 J; the mass of an electron = 9.11 x 10-31 kg)

the mass of an electron is 9.11 X10^-31 kg. if the brogile wavelength for an electron in a hydrogen atom is 3.31X10^-10 m how fast is the electron moving relative to the speed of light? the speed of light is 3.00X10^8 m/s .
