Homework Help: Max resultant of 2 vectors

  1. Oct 27, 2008 #1
    Max resultant of 2 vectors....

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

    What is the maximum possible resultant of two vectors with magnitudes of 20 and 8 units?

    3. The attempt at a solution

    i really honestly just dont get it, i know to some of you it may be really simple but can somone please explain this to me and how to get your answer?

    well think of the vectors like the hands of a clock, the way to add it together with the highest possible magnitude is when they are pointing the same direction, which is 28 units.

    If the two forces point in opposite directions, then you will get the minimum resultant force.

    Now knowing this, what do you think the forces will have to do to give the max resultant?
