The potential energy of an object is given by the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity (9.8 m/s^2), and h is the height of the object above some reference point.
Plugging in the numbers, we get:
PE = (45 kg)(9.8 m/s^2)(12 m) = 5,292 J
Therefore, the brown bear's potential energy is 5,292 J.
Answer: d) 5,292 J
