A velocity vector is displayed. Its magnitude is $75\,\text{m s}^{-1}$ and it makes an angle of $30^\circ$ east of north. What are the components of the velocity vector in the northerly and in the easterly directions?
- Anortherly $38\,\text{m s}^{-1}$, easterly $38\,\text{m s}^{-1}$
- Bnortherly $38\,\text{m s}^{-1}$, easterly $65\,\text{m s}^{-1}$
- Cnortherly $65\,\text{m s}^{-1}$, easterly $38\,\text{m s}^{-1}$
- Dnortherly $65\,\text{m s}^{-1}$, easterly $65\,\text{m s}^{-1}$
