A diver who has a mass of 68 kg climbs to a diving platform that is 7.5 m above the surface of a pool. How much gravitational potential energy does the diver have in relation to the pool’s surface?

Gravitational potential energy is calculated as PE = mgh, where m is mass, g is about 9.8 m/s², and h is height. Substituting the values gives PE = 68 × 9.8 × 7.5 = 4,998 J. Therefore, the diver has 4,998 J of gravitational potential energy, choice D.
