So the least potential energy is in the middle, where there is some spring and gravitational, but also kinetic. While at this equilibrium position, the mass is then given an initial push downward at v = 3. Then, the maximum speed of this hanging mass is fulfilled at the equilibrium position and its given by the following equation: (1) Where: is the spring constant which can be calculated by the Hooke's law: being the acceleration due gravity and the length the spring is streched. He uses a 2. What that means is that heavier objects require more force than lighter objects to make them move the same distance. A horizontal force F → causes the spring to stretch a distance of 5. when the mass hangs in equilibrium, the spring stretches x = 0. Any movement away from the equilibrium point results in a force toward the equilibrium point. The spring is then stretched an additional 0. 6 kg mass and then set in motion. 4 kg is hung from a vertical spring.
