A graph shows amplitude response curves for a mass-spring system under forced oscillations and damping. The mass is 250 g and the spring constant is 20 Nm⁻¹. The natural frequency, f₀, of the system is given by f₀ = (1 / 2π) * sqrt(k/m).

What is the value of the natural frequency on the graph?

This question uses a figure or table from the paper — you'll see it when you practise.
