Question

En = 14 джm=2кгh - ?​

Answer 1

Ответ:

Импульс p тела найдем как произведения его массы m = 2 кг и скорости v. Скорость найдем из уравнения кинетической энергии E = m * v^2 / 2.

v = √(2E/m)

p = m *v = m * √(2E/m) = 2 кг * √((2 * 25 кг*м^2/с^2) / 2кг) = 10 кг * м / с

Answer 2

It seems like you are trying to calculate the potential energy (En) of an object with a mass (m) of 2 kg and a height (h) without providing the value of the height.

The formula for potential energy is given by:

$En = m \times g \times h$

where $m$ is the mass of the object (2 kg in this case), $g$ is the acceleration due to gravity (approximately $9.81 \, m/s^2$), and $h$ is the height.

If you provide the height ($h$), I can help you calculate the potential energy.
