# A hammer hammer for hammering with its weight of 500 kg falls from a height of 10 m. What will be the potential

A hammer hammer for hammering with its weight of 500 kg falls from a height of 10 m. What will be the potential and kinetic energy of the hammer at a height of 4 m?

Given: m (weight of the hammer of the copra) = 500 kg; h0 (original fall height) = 10 m; h1 (considered height) = 4 m; g (acceleration due to gravity) ≈ 10 m / s2.

1) Determine the potential energy of the hammer head at a height of 4 m: En1 = m * g * h1 = 500 * 10 * 4 = 20 * 10 ^ 3 J (20 kJ).

2) Calculate the kinetic energy: Ek1 = En0 – En1 = m * g * h0 – m * g * h1 = m * g * (h0 – h1) = 500 * 10 * (10 – 4) = 30 * 10 ^ 3 J (30 kJ).

Answer: The potential energy of the pile driver is 20 kJ, and the kinetic energy is 30 kJ.
