Homework Help: What is his net displacement

  1. Sep 20, 2007 #1
    Please Help!!

    Jim walks 100m due south, 60m due east, and then 20m due north. What is his net
    displacement (both magnitude and direction)?

    According to his boots, his net displacement is of course 180 meter, but I know that is not what the (bad) problem designer had in mind :smile:

    Is this a homework problem?

    Also, does this occur on the Earth, or on a plane?

    I have no idea. I assume he mans displacement, instead of distance. :S
    Is the magnitude of distance the same as displacement?

    Hint: 60, 80 and 100 constitute a Pythagorean triple.

    Okay, I think I've got it.
    It's kinda like figuring out the hypotenuse?

    Thanks everyone : )

    Displacement means distance between original spot and final spot, "distance traveled" means the length of his entire pathway.
