Question

Тіло, підняте на висоту 25 м, має потенціальну енергію 500 Дж. Визначити його масу

Answer 1

Дано:
h=25м
Еп=500Дж
g=9,8
Знайти:
Еп=mgh→→→→m=Eп/(gh)=500Дж/(9,8*25)≈2,04кг

Answer 2

Calculation of Mass from Potential Energy

To determine the mass of an object raised to a height of 25 m with a potential energy of 500 J, we can use the formula for potential energy:

Potential Energy (PE) = mass (m) * gravitational acceleration (g) * height (h)

Given that the potential energy is 500 J and the height is 25 m, we can rearrange the formula to solve for mass:

mass (m) = Potential Energy (PE) / (gravitational acceleration (g) * height (h))

The gravitational acceleration on Earth is approximately 9.8 m/s^2.

Let's substitute the given values into the formula and calculate the mass:

mass (m) = 500 J / (9.8 m/s^2 * 25 m)

Calculating this, we find:

mass (m) ≈ 2.04 kg

Therefore, the mass of the object is approximately 2.04 kg.
