Springs & Elastic Potential Energy Video Lessons

Example

Problem: An engineer is designing a spring to be placed at the bottom of an elevator shaft.If the elevator cable breaks when the elevator is at a height h above the top of the spring, calculate the value that the spring constant k should have so that passengers undergo an acceleration of no more than 7.0 g when brought to rest. Let M be the total mass of the elevator and passengers.
