    We usually ignore the kinetic energy of the moving coils of a spring, but let's try to get a reasonable approximation to this. Consider a spring of mass M, equilibrium length L0, and spring constant k. The work done to stretch or compress the spring by a distance L is , where X = L - L0.Part AConsider a spring, as described above, that has one end fixed and the other end moving with speed v. Assume that the speed of points along...
