Suppose that the cyclist begins his journey from the rest from the top of a wedge with a slope of a degree above the horizontal. At point A (where it starts its journey), the energy is: Ea = m * g * h In other words, energy is only potential. At point B (located at the bottom of the wedge), the energy is: Eb = (1/2) * (m) * (v ^ 2) In other words, the energy is only kinetic. For energy conservation we have: Ea = Eb That is, we have that all potential energy is transformed into kinetic energy. Which means that the cyclist has less kinetic energy at point A because that's where he has more potential energy. answer: the cyclist has less kinetic energy at point A because that's where he has more potential energy.
