SUMMARY
The discussion focuses on calculating the apparent weight of a passenger in an elevator descending with constant acceleration. For a passenger with a mass of 72.2 kg, the scale reads 477.242 N when the elevator descends at 3.20 m/s². If the elevator descends at 9.8 m/s², the scale would read zero, indicating free fall. The effective acceleration on the passenger decreases as the elevator accelerates downward, resulting in a lower normal force, which is reflected in the scale reading.
