    vectors problems

    I dont quite get this problem. I know what the component vector form is but I dont know how this problem is done.
    Do you have to find the magnitude within it like Sqrt of x^2+y^2?
    Yeah.. Im kind of lost on this one. Thanks for the help if anyone can

    The "x" is the cos 210 = -sqrt(3)/2
    The "y" is the sin 210 = -1/2

    That means a unit vector is,
    -sqrt(3)/2 i - 1/2 j
    Multily this by 5 to get your answers.
