| To calculate the required potential energy of a given aircraft relative to the Earth, we apply the formula: En = m * g * h.
Variables: m is the mass possessed by a given aircraft (m = 2000 kg); g – acceleration due to gravity (g ≈ 10 m / s2); h – height (h = 160 m).
Let’s perform the calculation: Ep = m * g * h = 2000 * 10 * 160 = 3.2 * 10 ^ 6 J (3.2 MJ).
Answer: A given plane has a potential energy of 3.2 MJ relative to the Earth.
