A mass attached to a spring is suspended as shown. When the mass is at rest the spring is 12 centimeters long. The unstretched length of the spring is 8 centimeters. The mass is pulled down so that the spring length is 16 centimeters and then released. A graph of the spring length as a function of time is shown. Eight points are labeled A - H in the graph. At which point or points is the spring potential energy...
