Question

Чему равна масса меча , если на высоте 10м, он имел потенциальную энергию 50дж? Напиши те мне решение и дано плизз

Answer 1

Потенциальная энергия Eп=mgh, следовательно, m=En/gh=50/100=0.5 кг.

Answer 2

Given Information

The given information is that a sword at a height of 10m has a potential energy of 50J.

Solution

The potential energy (PE) of an object at a certain height is given by the formula: PE = mgh, where - m is the mass of the object, - g is the acceleration due to gravity (approximately 9.81 m/s^2 on the surface of the Earth), and - h is the height.

We can rearrange this formula to solve for the mass m: m = PE / (gh)

Substituting the given values: m = 50J / (9.81 m/s^2 * 10m)

Calculation

Let's calculate the mass using the given values: m = 50J / (9.81 m/s^2 * 10m) m ≈ 0.51 kg

Answer

The mass of the sword, if it had a potential energy of 50J at a height of 10m, is approximately 0.51 kilograms.
