Word problem

  1. Sep 12, 2011 #1
    Posted a picture... the picture consists of the word problem and the triangle is how I interpreted the problem....

    Vector A Components: (0,10)
    Vector B Components: ( Cos60*6,Sin60*6)

    Vector C Components: (Cos60*6 = 3 , Sin60*6 + 10 = 15) ... ( 3 , 15 )

    Vector C = (9 + 225) ^(1/2) = 15

    The true answer is 5.66....
    What did I do wrong?

    Correct up until here.

    You want to find vector [itex]C[/itex] such that [itex]B+C = A[/itex]. Do you understand why?

    Also you should note that the questions asks for the final displacement, which is a vector, not a scalar.

    Would the resultant vector be A at (0,10) because that is where the final position lies?

    Yes, but you want to find [itex]C[/itex]
