To find the vertical component of the launch velocity, we can use the following formula:

\[
v_y = v \cdot \sin(\theta)
\]

Where:
- \( v_y \) is the vertical component of the velocity,
- \( v \) is the initial velocity (65 m/s),
- \( \theta \) is the angle of launch (12°),
- \( \sin(\theta) \) is the sine of the angle.

### Now calculate it:

\[
v_y = 65 \cdot \sin(12^\circ)
\]

Using a calculator:

\[
v_y = 65 \cdot 0.2079 \approx 13.514 \, \text{m/s}
\]

So, the vertical component of the launch velocity is approximately **13.51 m/s**.
