Homework Help: Pythagorean Theorem to find the resultant

  1. Sep 11, 2008 #1
    A man walks 5 blocks east, then turns 10 blocks north, then walks 5 more block east.

    Total displacement____?

    is it...

    10^2 + 10^2 = c^2

    (Square root 200)=c^2

    14.14 = c^2

    is this right?

    Yes. Try to think of the paths as vectors where you can rearrange them how you choose.
