Halliday, Resnick & Walker — Force and Motion–I: Problem 44

A lamp hangs vertically from a cord in a descending elevator that decelerates at \(2.4\text{ m/s}^2\). (a) If the tension in the cord is \(89\text{ N}\), what is the lamp’s mass? (b) What is the cord’s tension when the elevator ascends with an upward acceleration of \(2.4\text{ m/s}^2\)?

📝 Solution Approach

Find: (a) If the tension in the cord is \; (b) What is the cord’s tension when the elevator ascends with an
