SUMMARY
The discussion centers on understanding the effective acceleration of gravity when an elevator accelerates downward. The user calculates the effective gravity as 9.81 m/s² minus the elevator's acceleration of 0.4 m/s², resulting in an effective gravity of 9.41 m/s². The user attempts to calculate the spring's stretch using the formula (-5.8*(9.81-0.41))/711, yielding -0.0766 m, which is incorrect. The key question remains whether the spring will stretch or compress under these conditions.
