Velocity Time graphs and Displacements

  1. Jan 14, 2009 #1
    1. The problem statement, all variables and given/known data
    How do i figure out the TOTAL displacement of this graph

    2. Relevant equations

    I'm guessing A=1/2bh
    and A = bh

    3. The attempt at a solution

    I've got no idea due to the line crossing the X axis

    ask yourself what velocities you're seeing. velocities include direction.

    the Y - axis is telling you the velocity of the object, whereas the x axis is telling you the time. you can tell the y axis is velocity because of the negative values towards the bottom of the y axis. you cant see the negative values but they're there. remember the equation v = d/t :)

    the line crossing the x-axis is simply the line that tells you the 0 point. it plays no significance unless your graphing line passes it. at the point that it passes that horizontal x axis line, that would tell you your velocity is 0 m/s.

    This problem is quite common in classrooms. The answer, along with the proper work, can be found at Physics Solutions.
