- ma bungee jump, a person is strapped to a rope that can stretch somewhat slowly so that their descent is safely slowed (so the rope acts as ONE GIANT elastic spring). Assume the rope has a SPRING CONSTANT of 45.3 N/m, and the jumper was 67.5 kg. a) if the MAXIMUM allowable NET ACCELERATION on the rider is 19.82 m/s, how far will the rope stretch (x), and what TENSION FORCE (F,) is that develops in the rope? (HINT: a Free-Body Diagram might help here) C214) b) How fast was the jumper travelling before the rope started stretching? (Think CONSERVATION OF ENERGY)

Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.
