35. With no loss of generality, we assume the electron is initially at rest (which simply means we are analyzingthe collision from its initial rest frame). If the photon gave all its momentum and energy to the (free)electron, then the momentum and the kinetic energy of the electron would becomep=hfcandK=hf ,respectively. Plugging these expressions into Eq. 38-51 (withmreferring to the mass of the electron)
