ANSWER:
5 m/s
STEP-BY-STEP EXPLANATION:
The vertical component would be the y component, which is given by the following formula:
[tex]v_y=v\cdot\sin \theta[/tex]replacing:
[tex]\begin{gathered} v_y=10\cdot\sin 30 \\ v_y=10\cdot0.5 \\ v_y=5\text{ m/s} \end{gathered}[/tex]The vertical component of velocity is 5 m/s
