Hi,
The question is:
The components of a vector V can be written as (V(x), V(y), V(z)). What are the components and length of a vector which is the sum of the two vectors, V(1) amd V(2). whose components are (8.0. -3.7,0.0) and (3.9,-8.1,-4.4)?
Work
For the components
V(x)= 8.0+3.9=11.9
V(y)=-3.7+-8.1=-11.8
V(z)= 0+-4.4=-4.4
That's all I have figured. I'm a little confused on the set up of this problem. to figure the length would I just use the Pythagorean theorem.
Please help and thank you
