Determine the Instantaneous Velocity of two coordinates on a graph

  1. Feb 24, 2013 #1
    I can't provide all the information, because I'm on my mobile phone. Here is a shot of the problem: ImageUploadedByPhysics Forums1361740440.419775.jpg

    The tangent of each curve is the slope, right? So how do we use that to find vf (instantaneous velocity) at 4s and 8s

    hi jmedina94! :smile:
    yes, the tangent is the slope

    and the slope is the velocity …

    so just count squares :wink:
