Question

Given the displacement vectors `A= (3i – 4j + 4k)m`, and `B= (2i + 3j – 7k)m`, how do you find the magnitudes of the vectors `C= A+B`?

Answer 1

I found: `C=A+B=(5i-j-3k)m`

Explanation:

You can add together the corresponding components to get:
`C=[(3+2)i+(-4+3)j+(4-7)k]m=`
`=(5i-j-3k)m`
