1. The problem statement, all variables and given/known data I know the answer to this question but I just need to know how I can prove this in a laboratory fashion... Here is the question: Why doe s a spring continue to vibrate and eventually come to rest when stretched and then released?? It has something to do with calculating efficiency but I dont know how to prove that in a lab. 2. Relevant equations I think you have to use Ee = 1/2 k x^2 F x = +/- k x 3. The attempt at a solution I know the answer to the question but I need to verify how I can prove this if asked to do so in a lab Thanks a lot!!
