SUMMARY
The discussion focuses on calculating the scale readings for a 60.0 kg person in an elevator accelerating at 3.5 m/s² both upward and downward. When accelerating upward, the scale reads 210 N, while during downward acceleration, the reading is 51 N. The calculations utilize the formula Fnet = ma, incorporating gravitational acceleration (9.8 m/s²) alongside the elevator's acceleration. The correct approach involves summing the gravitational force and the elevator's acceleration to determine the net force acting on the person.
