Homework Help: Hello Help Appreciated greatly

    In order to get this final equation
    of Displacement and time: [tex]v(t) = v_0 + \frac{1}{2} a t^2[/tex]

    How would I come about actually making this equation?

    Would it be a combination of the simple acceleration equation and Delta x equation .... with so algebra. BOOM answer?

    Thanks for your help!

    um... actually that isn't a correct equation. Were you thinking of one of these?
    x(t) &= x_0 + v_0 t + \frac{1}{2}a t^2 \\
    v(t) &= v_0 + a t

    WOW, thats how you do that! UH, I hate not having math hard core in my life and then BAM all of a sudden need to use it.

    Thanks a million :) !!!!!!!!!!

    Are you comfortable with doing integrals in calculus? You use fairly simple integrations to go from a(t) --> v(t) --> x(t), assuming constant acceleration (which is true in this case of gravity being the acceration).

    I used to about two years ago :(

    I'm lost at times but definitely getting there!
