I'm trying to figure out how to determine how long a spring should be to drop a known weight a known length? For example...10 foot drop, 1 lb weight, and I pick up a flexible spring from the hardware store (spring constant to be determined by Hooke's law experimentation), should I not be able to determine how long a spring to cut to just make the 1 lb weight drop to but not hit the floor?....much like a bungee question.

Welcome to Physics Forums.

Have you learned about conservation of energy in a physics class? You can equate the gravitational potential energy mgh with the potential energy of a stretched spring.
