Particle motion question

  1. Sep 24, 2006 #1

    okay...i labeled acceleration 0 -19 as c.


    for 19-23 we have


    0 -19 we have d=180.5c
    we have -823.5


    Am I doing it right in solving for C which is constant acceleration in 0 -19?

    edit: ok I know now it's not right.

    my final distance formula would be

    4700=-4.9x^2(for 19</x</23)+0.5cx^2(0</x</19)

    But i dont know how to put this in a real equation form...

    my second approach...



    and now i take the integral of all this and set it equal to 4700

    okay...so i think the following formula should work...

    [tex]\int_{0}^{19} {19c} dx + \int_{19}^{23} {-39.2} dx = 4700[/tex]

    grrrr. nope. Also sig figs matter.
    I got a 13.5 answer...and a 13.2 answer...this is getting fustrating.
