An engineer is designing a spring to be placed at the bottom of an elevator shaft.
if the elevator cable should break when the elevator is at a height h above the top of the spring, calculate the value that the spring stiffness constant k should have so that passengers undergo an acceleration of no more than 5.0 g when brought to rest. let m be the total mass of the elevator and passengers.
express your answer in terms of the variables h, m, and appropriate constants.
k = ?
