Kinetic energy and a hill

[mike_302]

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?
