# How do you find the unit vector that has the same direction as the vector below: v= 4j?

$\setminus \hat{j}$
unit vector $\setminus \hat{v} = \setminus \frac{\setminus \vec{v}}{| \setminus \vec{v} |}$
here that is simply $\setminus \hat{v} = \setminus \frac{\setminus 4 \setminus \hat{j}}{4} = \setminus \hat{j}$
