SUMMARY
The discussion centers on calculating the acceleration of an elevator and determining the weight of a person standing on a scale inside it. Luke's scale reads 0.968 kN when the elevator accelerates upward, and 1.215 kN when he picks up an 18.6 kg box. The calculated acceleration of the elevator is 3.48 m/s² upward. The confusion arises when calculating Luke's weight, where the correct approach involves using the formula F=MA to convert mass to weight, factoring in both gravitational and elevator acceleration.
PREREQUISITES
- Understanding of Newton's Second Law (F=MA)
