What is the work done when lifting a body weighing 300 g to a height of 12 m?

To calculate the value of the work performed (change in potential energy) when lifting the specified body, we apply the formula: A = ΔEp = mt * g * h.

Constants and variables: mt – mass (mt = 300 g = 0.3 kg); g – acceleration due to gravity (g ≈ 10 N / kg); h – change in the height of the specified body (h = 12 m).

Calculation: A = mt * g * h = 0.3 * 10 * 12 = 36 J.

Answer: The work required to lift the specified body by 12 m is 36 J.
