Question: When a certain force is applied to an ideal spring, the spring stretches a distance x from its unstretched length and does work W. If

When a certain force is applied to an ideal spring, the spring stretches a distance x from its unstretched length and does work W. If instead twice the force is applied, what distance (in terms of x) does the spring stretch from its unstretched length, and how much work (in terms of W) is required to stretch it this distance?
