Working out velocity for my coursework [Very confusing!]

  1. Jan 3, 2010 #1
    Hi guys,
    This is my first post on this forum and I was hoping you could help me.

    I'm in the middle of my coursework and I need help working out velocity, heres the info:

    Height (cm) Distance (cm)
    2.4 20
    3.7 30

    Average Time (Sec) Speed (cm/s) Velocity (cm/s)

    0.55 36.50 2.17
    0.80 37.50 2.69

    I have this really bad feeling that the velocity is wrong. Can anyone help me out?
    Pleaseee! I'm really counting on you lot!

    Hi,Physssics, welcome to PF. It would be beneficial if you could state the problem or experiment more clearly, so we can better see what you are looking for. Please show what formulas you are using and why, and how you are arriving at your answers, after first defining the problem. Use the format provided when you post.
