Pretend that an electron performs 1D motion in the field of the proton so that it's wavefunction is psi(x)=cos(x/a), where a=0.5 Angstrom. Remembering that the kinetic energy operator is (-hbar2/2m) d2/dx2 , compute the kinetic energy of the electron in eV (electronvolts). (I recommend comparing your answer to the energy of the 1s orbital of the hydrogen atom before you submit the answer. You should get the same order of magnitude!)
