Homework Help: Object moving towards or away from origin

  1. Mar 5, 2012 #1
    Object moving towards or away from "origin"

    1. The problem statement, all variables and given/known data

    I just want to confirm that I got this right:

    Given a s(t) relation of an object.
    The object moves along a straight line.
    At some time t, s(t) will tell me if the object is to the left or to the right of the origin.

    If s(t) is +:
    if if v(t) is +, then it is moving away from the origin.
    if v(t) is -, then it is moving back towards the origin.

    If s(t) is -:
    if v(t) is -, it is moving away.
    if v(t) is +, it is moving towards.



    2. Relevant equations



    3. The attempt at a solution

    if s(t) is a straight line then yes
