Answer 1

Еp= mgh
Ep=12,5×10×0,8=100Дж
Ответ 100 Дж

Answer 2

Calculation of Potential Energy

To calculate the potential energy of an object, we can use the formula:

Potential Energy = mass * gravitational acceleration * height

In this case, the mass of the object is 12.5 kg and the height is 80 cm (or 0.8 m). The gravitational acceleration can be approximated as 9.8 m/s^2.

Using the formula, we can calculate the potential energy of the object:

Potential Energy = 12.5 kg * 9.8 m/s^2 * 0.8 m

Calculating this, we find that the potential energy of the object is approximately 98 Joules.

Please note that the gravitational acceleration used in this calculation is an approximation and may vary depending on the location on Earth.
