Homework Help: Motion Position

  1. Oct 6, 2007 #1
    1. The problem statement, all variables and given/known data

    Consider the plot below describing motion along a straight line with an initial position of x = 10 m.


    What is the position at 6 seconds? Answer in m.

    The position at 2 seconds is 17 m.

    2. Relevant equations

    delta d = 1/2a delta t^2 + Vi delta t

    3. The attempt at a solution

    I didn't know whether to use 4 or 0 as the final velocity.

    delta d = 10 or 46

    The problem is much simpler than it looks. Remember from calculus how velocity and displacement are related.

    Hint: Remember that this may not necessarily be a constant acceleration problem.
