Question

You want to find the spring constant of a certain spring. You hang a series of masses on the spring, one at a time, allowing the spring to stretch slowly so that it comes to rest in equilibrium. For each mass you measure the amount the spring stretched from its original length. The data table shows the amount of stretch for each mass, and the graph shows stretch as a function of mass. From these data, and what you know about forces in equilibrium, find the k for this spring. (Hint: It will help to remember Newton #2 and to graph the data, and mind the units.)
