Find a vector of magnitude 3 in the direction of v=4i-3k

Step-by-step explanation:

The magnitude of a vector v = ai + bk is

In this problem, we have that:

Find a vector of magnitude 3 in the direction of v=4i-3k:

The first step is finding the unit vector of v, .

So

Magnitude 3, same direction.

We multiply the unit vector by +3, since it is in the same direction. If it was in the opposite direction, we would have multiplied by -3.

The answer is:

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p
