Where $\vec{g}^*$ is the acceleration of the inertial reference frame
$$ \vec{g}^*=\vec{g}-\vec{a} $$
Using the cosine law, we find the value of the modulus of the vector $\vec{g}^*$
−$$ (g^{*})^2=a^2+g^2-2agcos\alpha $$
+$$ (g^{*})^2=a^2+g^2-2ag\cos\alpha $$
Where
−$$ \boxed{g^*=\sqrt{a^2+g^2-2agcos\alpha}} $$
+$$ \boxed{g^*=\sqrt{a^2+g^2-2ag\cos\alpha}} $$
We substitute $(1)$ into the expression and find the period of oscillation of the pendulum
−$$ \boxed{T=2\pi\sqrt{\frac{l}{\sqrt{a^2+g^2-2agcos\alpha}}}} $$
+$$ \boxed{T=2\pi\sqrt{\frac{l}{\sqrt{a^2+g^2-2ag\cos\alpha}}}} $$

− $$T=2\pi\sqrt{l/{\sqrt{a^2+g^2-2agcos\alpha}}}$$
+ $$T=2\pi\sqrt{l/{\sqrt{a^2+g^2-2ag\cos\alpha}}}$$
