1. The cart in the figure (and in the video: https://youtu.be/gvPNrdfNo9g ) is attached to a light spring that can stretch and compress equally well. The cart and spring rest on a low-friction horizontal surface. The cart is shown at position III, at rest, not accelerating. The cart is pulled to position I (stretching the spring) and then released. It moves to position V, where it then reverses direction and returns again to position I. It repeats the motion. www. IV III
