Calculate the work that a person did by lifting a box with a load of 50 kg by 2 m.

We calculate the work of a person using the formula:
A = F * h, where F = Fт is the force of gravity acting on the box with the load (F = m * g, where m is the mass of the box with the load (m = 50 kg), g is the acceleration of gravity (we take g = 10 m / s ^ 2)), h is the lifting height of the box (h = 2 m).
Let’s calculate the work done by a person:
A = F * h = m * g * h = 50 * 10 * 2 = 1000 J = 1 kJ.
Answer: The work of lifting a box with a load is equal to 1 kJ.
