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 and acceleration of no more that 5.0 g when brought to rest. Let M be the total mass of the elevator and passengers.
