Question 852131: Given that: u = 6i−2j−8k and v = −7j−2k
q1) Find a vector in the same direction as u but equal in magnitude to v?
q2) Find a vector in the same direction as v but with a magnitude of 4?

1) Find the magnitude of v first.
Find the "u" unit vector by dividing it by its magnitude.
So the u unit vector would be
( ,,)
So then multiply the u unit vector by the magnitude of v.

.
2) The v unit vector is
( ,,)
Just multiply this by ,
