An ideal spring of negligible mass hangs vertically at equilibrium. You find that if you gently attach a 796-gram mass and allow the spring to stretch very slowly downward, the spring stops and remains at rest when it has stretched 15.3 centimeters from its starting position. What is the value of the spring constant, in newtons/meter?
