Average acceleration

  1. Oct 12, 2007 #1
    i cannot for the life of me figure out this question my teacher marked wrong a recent test, so if any one can hellp, thanks...ok, my teacher gave me a position vs time graph with a wavy line and asked to find the average acceleration between (t=14 seconds and 45 seconds)...sounds simple enough, but the problem is the t=14 seconds is located between two points, now i understand i could find two points and figure out the slope, t=14 seconds is at the top of hump on the wavy line, so if i tried to draw a line and find two points, it would be horizontal and still in between the two points on the position axis. this might be the most confusing problem ive had so any help would be great. :approve:

    It would be more helpful if you included a diagram. I can't picture what you're trying to describe.
