Question

Can someone help me?!!!!!

Answer 1

7 units, north

Step-by-step explanation:

This is a problem of vector subtraction. We have:

- Vector A: magnitude 2 units, direction to the north

- Vector B: magnitude 5 units, direction to the south

If we take the north as positive direction, we can write

`A = +2\\B=-5`

Since we want to find
`A-B` (vector subtraction), we have to change the sign of B, so we find:

`A-B=+2-(-5))=+2+5=+7`

And the positive sign means the direction is north.
