Answer:

U = 18,785 J

Step-by-step explanation:

Elastic Energy

Elastic energy is energy stored in an object due to a force that temporarily changes its shape, such as shrinking or stretching.

The elastic energy can be calculated as follows:


\displaystyle U=(1)/(2)k(\Delta x)^2

Where k is the spring constant, and \Delta x is the change in the size of the spring.

The bungee cord stretches \Delta x =17 m, and k=130 N/m, thus:


\displaystyle U=(1)/(2)130(17)^2

U = 18,785 J
