The stiffness of a light undeformed elastic spring is k = 250N / m.

The stiffness of a light undeformed elastic spring is k = 250N / m. The spring is compressed by | ΔL | = 20 cm. Determine the potential energy of the compressed spring.

Initial data: k (stiffness of a light undeformed elastic spring) = 250 N / m; | ΔL | (spring modulus) = 20 cm (0.2 m).

The potential energy of a compressed light spring can be calculated by the formula: En = 0.5 * k * ΔL ^ 2.

Let’s make the calculation: En = 0.5 * 250 * 0.2 ^ 2 = 5 J.

Answer: The potential energy of a light elastic spring is 5 J.
