Question

На какую высоту нужно поднять тело массой 500г чтобы потенциальная енергия тела увеличилась на 30Дж?

Answer 1

Епот=mgh=0,5*10*h=5h=30=>h=6

Answer 2

Е=mgh

h=E/mg=30Н/0.5кгх9.8Н/кг=6метров

Answer 3

Calculating the Height to Increase Potential Energy

To calculate the height to which a body with a mass of 500g needs to be raised in order to increase its potential energy by 30J, we can use the formula for potential energy:

Potential Energy (PE) = mass * gravity * height

Where: - PE is the potential energy, - mass is the mass of the body, - gravity is the acceleration due to gravity, and - height is the vertical distance the body is raised.

We can rearrange the formula to solve for height:

height = PE / (mass * gravity)

Substituting the given values: - Potential Energy (PE) = 30J - mass = 500g = 0.5kg (since 1kg = 1000g) - gravity = 9.81 m/s^2 (approximate value on the surface of the Earth)

We can now calculate the height using the given values.

Calculation

height = 30J / (0.5kg * 9.81 m/s^2)

height ≈ 30J / 4.905 ≈ 6.12 meters

So, the body with a mass of 500g needs to be raised to a height of approximately 6.12 meters in order to increase its potential energy by 30J.
