When the spring is stretched by 0.1 m, an elastic force of 30 N arises in it, which is equal to the coefficient of elasticity of the spring.

To calculate the coefficient of elasticity of a given spring, we apply Hooke’s law: Fcont. = k * Δx, whence k = Fcont. / Δx.
Variable values: Fcont. – the emerging elastic force (Fel. = 30 N); Δx – tensile deformation (Δx = 0.1 m).
Let’s perform the calculation: k = Fcont. / Δx = 30 / 0.1 = 300 N / m.
Answer: The coefficient of elasticity is 300 N / m.
