I would expect his kinetic energy (KE) to be at its highest when he arrives at the bottom of the ramp. This is because as he descends the ramp, the gravitational potential energy (PE) he possesses is being converted into kinetic energy due to the acceleration of gravity. Therefore, his KE would be maximum at the bottom of the ramp.

The potential energy (PE) at the bottom would be lower than at the top of the ramp, as he has lost some of his initial potential energy while descending. This PE is converted into kinetic energy as he moves downwards. The conversion of potential energy to kinetic energy is consistent with the principle of conservation of energy.
