Question

Пружина жесткостью 1600 н/м растянута на 30 см какова потенциальная энергия!

Answer 1

Ер = k·x²/2 = 1600·(0,3)² / 2 = 72 Дж

Ответ 72 Дж

Answer 2

Calculation of Potential Energy

To calculate the potential energy of a spring, we can use the formula:

Potential Energy = (1/2) * k * x^2

Where: - k is the spring constant (also known as the stiffness) in N/m. - x is the displacement of the spring from its equilibrium position in meters.

In this case, the spring constant is given as 1600 N/m and the displacement is 30 cm, which is equal to 0.3 meters.

Plugging these values into the formula, we get:

Potential Energy = (1/2) * 1600 N/m * (0.3 m)^2

Calculating this expression, we find:

Potential Energy = 72 Joules

Therefore, the potential energy of the spring with a stiffness of 1600 N/m and a displacement of 30 cm is 72 Joules.
