$R_e$ I assume is the radius of the Earth, but the slides don't explain themselves any further than this.

comment Why 'max' in $hf=\phi+{1\over{2}}mv_\text{max}^2$?
Are you saying that if we form an equation for the instant of liberation then we'd drop the $\text{max}$ subscript, but we include it because energy loss creeps in before the the electron is liberated from the bulk of the material?
