How much kinetic engergy in eV must an election beam have to be able to excite a quantum oscillator from its ground state to two levels above the ground state if the mass is 3e-26kg and the spring stiffness is 80N/m?

All I can find is the spacing between the energy levels, I have no idea how to find K. The answer is 6.8e-2 J, but I don't have a clue how to get there.
