Question

this photo shows a system that consists of a person on a diving board. what change could you make to the system that would increase its total energy? a. increase the rigidity of the diving board. b. increase the height of the diving board. c. decrease the height of the diving board.

Explanation:

The total energy of the system (person + diving board) includes gravitational potential energy (PE = mgh, where m is mass, g is gravity, h is height). Increasing the height (h) of the diving board increases the potential energy of the person (and system), thus increasing total energy. Rigidity affects elasticity, not total energy here. Decreasing height would lower potential energy. So option B is correct.

Answer:

B. Increase the height of the diving board.
