...Express (14N, 240°) as a column vector.
(−7−7√3)
(7√37√3)
(−7√3−7)
(7−7√3)
Correct answer is A
F=(FxFy)=(FcosθFsinθ)
(14N, 240°) = \begin{pmatrix} 14\cos 240 \\ 14\sin 240 \end{pmatrix}
= \begin{pmatrix} 14 \times -0.5 \\ 14 \times \frac{-\sqrt{3}}{2} \end{pmatrix}
= \begin{pmatrix} -7 \\ -7\sqrt{3} \end{pmatrix}
