The potential energy of an object is given by the formula PE = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height.
In this case, the mass of the water tank is 38,000 kilograms and the height is 58 meters. The acceleration due to gravity is approximately 9.8 m/s^2.
Plugging these values into the formula, we get:
PE = (38,000 kg)(9.8 m/s^2)(58 m)
= 21,599,200 J
So the potential energy of the water tank is 21,599,200 J.
Therefore, the correct answer is:
21,599,200 J
