The spring with stiffness K = 60 N / m was stretched by 20 cm. Determine the potential energy of the spring.
| December 28, 2020 | education
We calculate the potential energy of the spring using the formula:
Ep = (k * x²) / 2, where k is the stiffness of the spring (k = 60 N / m), ∆l is the amount of spring deformation (∆l = 20 cm = 0.2 m).
Let’s calculate the potential energy of the spring:
Ep = (k * x²) / 2 = 60 * 0.2² / 2 = 60 * 0.04 / 2 = 1.2 J.
Answer: The potential energy of the spring is 1.2 J.
