What height can a stone thrown upwards with a mass of 0.3 kg reach if its initial velocity

What height can a stone thrown upwards with a mass of 0.3 kg reach if its initial velocity kinetic energy was equal to 120J

Initial data: m (mass of a stone thrown upwards) = 0.3 kg; Ek (kinetic energy of the stone at the moment of throwing upwards) = 120 J.

Reference values: g (acceleration due to gravity) ≈ 10 m / s2.

At the moment when the stone reaches its maximum height, the equality of energies will be true: Ek = En and Ek = m * g * h, whence h = Ek / (m * g).

Calculation: h = Ek / (m * g) = 120 / (0.3 * 10) = 40 m.

Answer: The stone can reach a height of 40 meters.
