Determine the potential energy of a load with a mass of 2 tons, at a height of 3 m.

The given tasks: m (mass of the considered cargo) = 2 t (2 * 10 ^ 3 kg); h (height at which the load should be) = 3 m.

Reference data: g (acceleration due to gravity) ≈ 10 m / s2.

The potential energy of the body in question can be determined by the formula: En = m * g * h.

Calculation: En = 2 * 10 ^ 3 * 10 * 3 = 60 * 10 ^ 3 J (60 kJ).

Answer: At a height of 3 m, the load in question will have a potential energy of 60 kJ.
