Therefore, $\begin{align} & \mathbf{v}=\frac{1}{4}\cos {{200}^{\circ }}\mathbf{i}+\frac{1}{4}\sin {{200}^{\circ }}\mathbf{j} \\ & =\left[ \frac{1}{4}\times \left( -0.9397 \right) \right]\mathbf{i}+\left[ \frac{1}{4}\times \left( -0.3402 \right) \right]\mathbf{j} \\ & =-0.23\mathbf{i}-0.09\mathbf{j} \end{align}$
