+ <h3>Solution</h3>
+ <p>
+ <p>The coin has a velocity $\vec{v}_{rel}$ directed at an angle $\alpha$ to the horizon in the inertial reference frame of the wedge, which moves horizontally with a velocity $\vec{v}_{cl}$.</p>
+<p>Then the absolute velocity $\vec{v}$ in the inertial reference frame will be equal to the vector sum of $\vec{v}_{rel}$ and $\vec{v}_{cl}$</p>
+<p class="exp">$$\vec{v} = \vec{v}_{cl} + \vec{v}_{rel}$$</p>
