Kineticn energy for hydrogen atom the negative energy of the incident light , So the atom will be ionised and having kinetic energy of -14eV

If a photon of energy 14 eV is incident on an H-atom,atom will be ionized and electron will have a kinetic energy of 0.4 eV.
The energy of electron in the ground state of hydrogen is 13.6 eV. The difference14eV−13.6eV=0.4eVrelates to the kinetic energy.
