Ответ:
option D
4998 J
Step-by-step explanation:
Given in the question that,
mass of the diver = 68 kg
distance of the diver from the surface of a pool = 7.5 m
The gravitational potential energy of an object is given by
GPE = m(g)(h)
here,
m is the mass of the diver
g is the acceleration due to gravity = 9.81m/s²
h is the height from the surface
Plug values in the formula to calculate GPE
GPE = 68(9.8)(7.5)
= 4998 J
Therefore, the gravitational potential energy of the diver with respect to the surface of the pool is 4998 J
