A stone weighing 500 grams freely fell to the ground from a height of 20 meters. Determine the maximum kinetic energy of the stone?
Initial data: m (mass of the stone taken) = 500 g (0.5 kg); h (height from which the taken stone fell) = 20 m.
Reference values: g (acceleration due to gravity) ≈ 10 m / s2.
The maximum kinetic energy of the taken stone will be equal to its potential energy at the height from which it fell: Ek = En = m * g * h.
Calculation: Ek = 0.5 * 10 * 20 = 100 J.
Answer: The maximum kinetic energy of the stone taken is 100 J.
