The plane flies at an altitude of 160 m, what energy relative to the Earth does it have, the weight of the plane is 2000 kg.

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.
