\section{Kinematics}

\Problem A ship moves along the equator to the east with velocity $v_0 = 30$ km/hour. The southeastern wind blows at an angle $\phi = 60^{\circ}$ to the equator with velocity $v = 15$ km/hour. Find the wind velocity $v'$ relative to the ship and the angle $\phi'$ between the equator and the wind direction in the reference frame fixed to the ship.

    \begin{center}
    \begin{tikzpicture}
    \draw[->](0,0) -- (-1,1) ;
    \draw[->](-0.2,1) -- (-1,1) ;
    \end{tikzpicture}

现在，正如您在图片中看到的那样，那些矢量头变得一团糟，那么有没有解决方案可以美化它或至少使它可读。
