Chapter 9: Q9-2Q (page 230)

A bungee jumper momentarily comes to rest at the bottom of the dive before he springs back upward. At that moment, is the bungee jumper in equilibrium? Explain.

Short Answer

Expert verified

Yes, the bungee jumper is in equilibrium.

Step by step solution

01

Meaning of equilibrium

Equilibrium may be described as the situation in which the forces acting in opposite directions are perfectly balanced so that there is no tendency to change.

In this situation, the value of the net force working on the system is equivalent to zero.

02

Explanation for the equilibrium state of a bungee jumper

The bungee jumper is in equilibrium at the bottom of the dive because his weight acting vertically downward is balanced by the tension in the ropes on either side of him.

If he was not in equilibrium, he would have either come down if his weight was greater, or gone up if the tension was larger than his weight. As his body continues to be at rest, he is supposed to be in a state of equilibrium.
