The components of the vector v are given as:
[tex]\begin{gathered} v_x=v\cos \theta \\ v_y=v\sin \theta \end{gathered}[/tex]
where v is the magnitude of the vector and theta is the angle.
In this case we have v=253 and theta=55.8°, plugging this values into the y component we have:
[tex]\begin{gathered} v_y=253\sin 55.8 \\ v_y=209.25 \end{gathered}[/tex]
Therefore the y component is 209.25 meters.
