Final answer:
To calculate the gravitational potential energy gained, use the formula E = mgh, where E is the gravitational potential energy, m is the mass (in kilograms), g is the acceleration due to gravity, and h is the height (in meters). Based on the given information, the height is not provided, so the exact gravitational potential energy gained cannot be determined.
Step-by-step explanation:
To calculate the gravitational potential energy gained, we use the formula E = mgh, where E is the gravitational potential energy, m is the mass (in kilograms), g is the acceleration due to gravity (approximately 9.8 m/s²), and h is the height (in meters).
Based on the given information, the mass of the eagle is approximately 1,500 kg. However, the height is not provided, so we cannot determine the exact gravitational potential energy gained. Therefore, none of the given options (a, b, c, d) can be confidently chosen as the correct answer.
