Position and Displacement question.

  1. Jun 30, 2012 #1
    1. The problem statement, all variables and given/known data
    You walk to the corner store after school to buy a carton of milk before going home. The store is 750 m south of the schoo, and your house is 625 m north of the school. What is your net displacement.


    2. Relevant equations

    dT=d1+d2

    formula for displacement


    3. The attempt at a solution

    625-750
    = -125

    I do not think this is right. Please help!

    No, it isn't. The first thing you need to do is review the meaning of "net displacement". You started at school and wound up at home. How far from your starting point are you?

    From school to home I am 625 m away.

    hi ybhathena! :smile:
    then that's the answer! :biggrin:

    (except that displacement is a vector, so you need to specify the direction also :wink:)
