I normally wouldn't be asking this, but we never went over this type of problem in class. Watch it be something obvious.
I have to find a vector v given magnitude:
||v|| = 5
and direction:
u = <3, 3>
No clue what to do. I tried to find the unit vector of <3, 3>. Obviously that didn't work because I got a completely different vector than what is given as the answer.
