Simple speed problem

  1. Sep 23, 2008 #1
    Diagram Link: http://picasaweb.google.com/swede5670/Physics#5249363825478610690
    (If the text is too small click on the magnifying glass on the upper right corner of the picture)

    I have no idea how to do the problems and my worksheet is due tomorrow. I'm having the most problem on the first diagram but I am equally befuddled with the last two. I appreciate any help on the problem.

    Welcome to PF.

    All three pictures are the same.

    How fast is the cart going over the segment B to D?

    Yes, all the diagrams are the same but the text is different on each one.
    From B to D was it going 1 meter per second? It starts at 2.1 seconds and ends at 3.1 seconds and the distance is 1 meter.
    I'm just confused about the speed at A. Should I say zero? The cart doesn't appear to be moving, I'm not sure what hes asking.

    I don't see that asked. Your picture only shows the same image repeated 3 times.

    I just checked the picture and everything seems fine. Use the zoom button located on the top right corner of the picture to zoom in on the text. Each text prompt asks for a different position at points A, B and D

    If you know the speed at D, what is the speed at B?

    At A what does at rest mean?
