The truck crane, lifting a load weighing 1.5 tons, performed the work of 22.5 KJ. To what height is the load lifted?

To find the value of the lifting height of the load, we apply the formula: A = mg * g * h, from where we express: h = A / (mg * g).

Variables and constants: A – work performed by the used truck crane (A = 22.5 kJ = 22.5 * 10 ^ 3 J); mg is the mass of the lifted load (mg = 1.5 t = 1.5 * 10 ^ 3 kg); g – acceleration due to gravity (g ≈ 10 m / s2).

Calculation: h = A / (mg * g) = 22.5 * 10 ^ 3 / (1.5 * 10 ^ 3 * 10) = 1.5 m.

Answer: The truck crane used had to lift the load to a height of 1.5 m.
