Energy and Momentum: Spring Goes Around Track

The 0.31 kg mass slides on a frictionless wire that lies in the vertical plane. The ideal spring attached to the mass has an equilibrium length of 80 mm and its spring constant is 120 N/m. The mass is released at point A, from rest. Calculate the minimum distance b, if the mass is to slide all the way around the loop to point B.

So once the mass is in the loop, the spring is in equilibrium. This means that there is no energy on the spring. ...

Solution Summary

The solution provides simple, easy-to-follow calculations that will lead the reader to the answer of how far a mass attached to a spring will slide under the conditions given in the question.
