Answer :
The luge and rider lose 88,750 J of energy as they go down the Pyeongchang track.
The amount of energy lost can be calculated using the principle of Conservation of energy .
The initial potential energy of the luge and rider is equal to the final kinetic energy at the bottom of the track.
The formula for potential energy is mass times gravity times height, and the formula for kinetic energy is 0.5 times mass times velocity squared.
By plugging in the given values, we can calculate that the initial potential energy is 117,129 J and the final kinetic energy is 205,879 J.
Therefore, the energy lost is 205,879 J - 117,129 J = 88,750 J.
