Question

how do I solve this? (I know how to add vectors, find magnitude, but I don't get what I have to do here)

Answer 1

subtract v1 from v2 to find v current.

Answer 2

I was trying to do that, this is the only way to find the current?

Answer 3

Yes and no. It is the only way to find it, but there's like 3 different ways to do that.

Answer 4

You can do it graphically (by drawing), you could use Pythagorean theorem, or you could use algebra (vectors/matrix).

Answer 5

I used pythagorean theorem.. and the vector v1=0i+8j ?

Answer 6

yes, i believe so

Answer 7

ok, I will try again, thank you

Answer 8

just give me a call when you need more help with it. Vectors can be a little tricky, but once you master them they can be of great use.

Answer 9

alright, thanks!
