| **What is the potential energy (Eк) with a mass (m) of 30 kg raised above the ground to a height (h) of 1.5 km. gravitational acceleration (g) is taken equal to 10H / kg.**

To calculate the value of the potential energy of the lifted body, we use the formula: Ep = mt * g * h.

Constants and variables: mt is the mass of the lifted body (mt = 30 kg); g is the acceleration of gravity (according to the condition, we take g = 10 N / kg); h – height above the ground (h = 1.5 km = 1.5 * 10 ^ 3 m).

Calculation: Ep = mt * g * h = 30 * 10 * 1.5 * 10 ^ 3 = 450 * 10 ^ 3 J = 450 kJ.

Answer: The potential energy of the lifted body is 450 kJ.
