The Attempt at a Solution
I do not understand why is mgh2 is being subtracted from the overall equation instead of added.
I am able to construct each of the work components but when building the overall equation I'm having a problem of understanding when is each component should be added or subtracted (except for the friction which make sense to subtract) [/B]
