SUMMARY
The discussion centers on calculating the change in gravitational potential energy (PE) for a skier using the formula ΔPE = mgh. The skier, weighing 70.0 kg, rides a lift that is 2860 m long at an angle of 14.8° with the horizontal. The angle is irrelevant for the potential energy calculation, as only the change in height is necessary. Participants clarify that the formula simplifies to ΔPE = mgΔh, emphasizing that the angle is a distraction.
