Reverse Bungee.?

Question

could you please enlighten me on the energy aspects involved with the reverse bungee?

thank you!

Answer 1

When the seat (which takes the form of a spherical cage) is fastened into the down position, an electromechanical latch is secured. The elastic ropes that are attached to the cage are also attached to the tops of two towers, and in the down position they are very tightly stretched. As a result, there is a large amount of elastic potential energy (EPE) stored in the ropes. They are exerting an upwards force on the cage, which is matched by the force of the electromechanical latch. When the electromagnet is released, equilibrium is lost and the seat accelerates upwards at about 4.8 g, where g = 9.8 m/s, the acceleration due to gravity at Earth's surface. The elastic potential energy in the ropes is converted into kinetic energy (KE, energy of motion) as the seat accelerates and into gravitational potential energy (GPE) as the seat increases its altitude. As the seat rises, it will achieve maximum velocity when it reaches equilibrium, at the point where the now-only-slightly stretched ropes provide an upwards force exactly equal to the downwards force of gravity. Later, the seat will reach its maximum vertical position, where KE is again zero (because the seat will have stopped rising and is about to fall, meaning it has zero velocity for an instant), gravitational potential energy is maximized, and the sum of EPE and GPE is equal to the EPE that was in the ropes at the bottom position. The sum of EPE, KE, and GPE will have this value during the entire motion, if we ignore air resistance and friction.

You mean like a giant rubber band hanging from a bridge or something that shoots you up in the air from below it?
