Homework Help: Kinetic energy and a hill

  1. Nov 14, 2009 #1
    1. The problem statement, all variables and given/known data

    My attempt at a solution was to say:

    Eki = Ekf + Eg

    and my Ek 's all has 1/2 on them... other than that, my solution is essentially the same thing.
    I end up with sqrt( vi2 - sg(delta)h ) = vf

    What's up with this?

    The solution in the pdf file looks good and has the same answer as in your post (except for an extra "s" which must be a typo). What exactly is the question you are asking?
