A body weighing 2.5 kg was thrown vertically upward. To what height will the body rise if at the moment

A body weighing 2.5 kg was thrown vertically upward. To what height will the body rise if at the moment of throwing it was told a kinetic energy of 500J? Disregard air resistance.

To find the height to which a given body was supposed to rise, we use the equality: Ek = Ep (the law of conservation of energy) = m * g * hx, from where we express: hx = Ek / (m * g).

Variables and constants: Ek – kinetic energy imparted to a given body (Ek = 500 J); m – mass (m = 2.5 kg); g – acceleration due to gravity (g ≈ 10 m / s2).

Calculation: hx = Ek / (m * g) = 500 / (2.5 * 10) = 20 m.

Answer: The body will rise 20 meters.
