Extremely simple question, but not for me!

  1. Jul 31, 2007 #1
    I'm currently studying Kinematics but I've been out of H.S. for nine yrs. now. I know this is more of a math problem but could someone pls. show me how ;


    a=(vf-vi) / t can be manipulated to find vf, as vf = vi + at

    Much appreciated!!!!

    Welcome to the forums.

    I think your equations aren't quiet correct. Shouldn't they really be the following?

    a = (vf - vi) / t

    vf = vi + at

    I think that's what he's got.

    Like this:

    [tex]a = \frac{(v_f - v_{i})}{t}[/tex]

    [tex]at = v_f - v_i[/tex]

    [tex]v_f = v_i + at[/tex]
