Question

Пружина жесткостью 104 Н/м растянута на 4 см. Какова потенциальная энергия упругой деформации пружины?

Answer 1

Δх=0,04 м

k=104 Н/м
W=k*Δx²/2=104*0.04²/2=0.083 Дж

Answer 2

Calculating Potential Energy of Elastic Deformation

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

Potential Energy (PE) = 0.5 * k * x^2

Where: - k = spring constant (in N/m) - x = displacement from the equilibrium position (in meters)

Given: - k = 104 N/m - x = 0.04 m (4 cm)

Calculation

Using the given values, we can calculate the potential energy of the elastic deformation of the spring:

PE = 0.5 * 104 * (0.04)^2

PE ≈ 0.5 * 104 * 0.0016

PE ≈ 0.0528 Joules

So, the potential energy of the elastic deformation of the spring is approximately 0.0528 Joules.
