Determine the potential energy of a body weighing 2 kg at a height of 3 m from the surface of the Earth. The zero level of potential energy is chosen on the surface of the Earth.
Data: mt (weight of the indicated body) = 2 kg; h (height from the surface) = 3 m; g (acceleration due to gravity) ≈ 10 m / s2; according to the condition, the zero level is measured from the surface of the Earth.
The formula for calculating the potential energy of the specified body: Ep = mt * g * h = 2 * 10 * 3 = 60 J.
Answer: The potential energy that the indicated body has acquired is 60 J.
