<h3>Solution</h3>
<p>
Since the oscillations are harmonic, the greatest velocity $v_0$ can be found through the greatest deviation from the equilibrium position $x_0$. To do this, we take the derivative of the solution to the equation of harmonic oscillations
−$$ v=\frac{dx}{dt}=\frac{d}{dt}\left(x_0\sin\omega t\right)=x_0\omega \cos\omega t $$
+$$ v=\frac{dx}{dt}=\frac{d}{dt}\left(x_0\sin\omega t\right)=x_0\omega\cos\omega t $$
From which it follows that the maximum speed $v_0$ is equal to
−$$ v_0=x_0\omega $$
+$$ v_0=x_0\omega$$
Substituting the value for the cyclic frequency $\omega$ of the spring pendulum $\left(\omega = \sqrt{\frac{k}{m}}\right)$ obtained earlier from <a href="../3.1.2">3.1.2</a>
$$ v_0=x_0\sqrt{\frac{k}{m}}\Rightarrow\boxed{k=\frac{v_0^2m}{x_0^2}} $$
b) The restoring force in these harmonic oscillations will be the elastic force of the spring $F=-kx$, since in any case in a conventional spring pendulum the restoring force is equal to the elastic force of the spring. Then we find the work of this force as in <a href="../3.1.2">3.1.2</a>:
