Question

Камень бросают вертикально вверх с начальной скоростью 20км/чна какую высоту поднимется камень

Answer 1

Vo =20 км/ч ≈ 5,6  м/с
H = V² / (2*g) = 5,6² / (2*9,8) ≈ 1,6 м

Answer 2

Calculation of the Height Reached by a Stone Thrown Vertically Upwards

To calculate the height reached by a stone thrown vertically upwards, we can use the equation for gravitational potential energy. The initial kinetic energy of the stone is converted into potential energy as it moves upwards against the force of gravity.

The equation for gravitational potential energy is:

PE = mgh

Where: - PE is the gravitational potential energy - m is the mass of the stone - g is the acceleration due to gravity (approximately 9.8 m/s^2 on Earth) - h is the height reached by the stone

To find the height reached by the stone, we need to know the initial velocity of the stone. However, the initial velocity of the stone is not provided in the question. Therefore, we cannot calculate the exact height reached by the stone without this information.

If you have the initial velocity of the stone, please provide it so that we can calculate the height reached accurately.
