Homework Help: Question on vectors.

1. Dec 1, 2007

What is the maximum resultant of a 1 centimeter vector and a 4 centimeter vector? What is the minimum?

This questions is like foreign to me. I am rather keen with vectors; however, I have never seen a question like this.

Ok, so first you should ask yourself "what is the resultant of two vectors."

When you add the two vectors head to tail, what's the longest vector you can end up with? What is the shortest one?

5 and 4?

5 is correct, 4 is not. Try $$\vec{V_{1}} + \vec{V_{2}}$$ where $$\hat{V_{1}} = - \hat{V_{2}}$$.

The vectors can have an opposite direction.

Ok...how did you get 5 and what was your reasoning behind it?

4+1=5

if that would give you the largest resultant...what do you think would give you the least?
