magnitude: ||v||= 5
direction: u=<3,3>

$\vec v $ has the same direction as $\vec u$ , can you find the unit vector of $\vec u$?

anonymous · Answer

would that be the square root of 18? I know there is another step to solving for it but I don't know it

loser66 · Answer

Hint: unit vector of vector u, namely $\vec e_u =\dfrac{<3, 3>}{||u||}$

loser66 · Answer

this vector has the length 1, if ||v|| = 5, just *5 to get $\vec v$

anonymous · Answer

so after finding the unit vector I just multiply by 5?

loser66 · Answer

yes

hmm ok
