Answer

The Young’s modulus for a bungee cord is smaller than that for ordinary rope.

Work Step by Step

From equation 9–4 we see that for a given applied force, a small Young’s modulus means that the object stretches a relatively large amount. All else being equal, a bungee cord stretches more than a same-sized ordinary rope. The bungee cord material has a smaller Young’s modulus.
