1. The problem statement, all variables and given/known data

When finding the resultant velocity in a problem what does the resultant stand for

2. Relevant equations

((x2+y2)1/2

3. The attempt at a solution
I understand I use the equation above to find the resultant velocity but is the resultant the same thing as displacement and if so why would there be a velocity to it because all displacement has to do with is position??!

Please someone explain this to me I've asked about 7 people this question today and no one could give me a good answer.

Re: Resultants

In your relevant equation, it's ((V_x^2 + (V_y ^2)) ^1/2 = V_resultant. In other words, the resultant velocity is the square root of the sum of the squares of the x and y components of the velocity. Velocity and displacement are mathematically related, but they are not the same.
