Max and min resultants?

  1. Sep 20, 2007 #1
    1. The problem statement, all variables and given/known data

    what is the maximum possible resultant of two vectors with magnitudes of 4 and 5 units? what is the minium possible resultant?

    2. Relevant equations

    3. The attempt at a solution

    so i think that the max resultant would be 9 units and the minium resultant would be 4 units?

    max=9 is correct, because that is when they line up parallel and add. The minimum is not 4, though. How could you line up the two vectors to get a smaller result?

    Max is correct. Min is wrong,
    If you moved 5 units in one direction and 4 in another, how close could you get to the starting point?

    so if you went up 5 then back down four that would leave you with one?
