Base your answers to questions 1 through 5 on the information below and on your knowledge of physics.

Bungee Jumping One of the highest commercial bungee jumps in the world is located at the Macau Tower, near Hong Kong, as shown in Diagram 1. The jumping platform is 233 meters above the ground.

Diagram showing the Macau Tower, including a labeled jumping platform and a height measurement of 233 meters to the base.

Bungee jumpers at the Macau Tower ride an elevator from the ground floor to the jumping platform, as shown in Diagram 2.

Assuming no mechanical energy is removed from the jumper-bungee cord-Earth system during the fall, develop a mathematical model that could be used to represent the energy transformation starting at the jumping platform and ending at the lowest point. [1]

HS-PS3-1

The bungee jumper rebounded upward after momentarily coming to rest at the lowest point. The bungee jumper did not return to the height of the jumping platform after rebounding, as shown in Diagram 5.

Considering the jumper-bungee cord-Earth system, which statement correctly describes why the jumper does not return to the initial height of the platform after rebounding?

Air resistance causes an increase in the mechanical energy of the system.

Air resistance causes a decrease in the mechanical energy of the system.

The gravitational force acting on the jumper causes a decrease in the mechanical energy of the system.

The gravitational force acting on the jumper causes an increase in the mechanical energy of the system.
