A stone weighing 0.2 kg falls from a height of 5 m and is pressed into the ground by 5 cm. What is the force. soil resistance?

The soil resistance force can be calculated using the formula:
Fc = Еcomplete. / h, where Ecomplete. – the total energy of the stone (the stone fell without initial velocity and the total energy of the stone will be equal to the potential), h – the height of the stone being pressed into the ground (h = 5 cm = 0.05 m).
Epol. = Ep = m * g * h1, m is the mass of the stone (m = 0.2 kg), g is the acceleration of gravity (g = 10 m / s²), h1 is the height of the fall of the stone (h1 = 5 m).
Fc = m * g * h1 / h = 0.2 * 10 * 5 / 0.05 = 200 N.
Answer: The force of soil resistance is 200 N.
