AP Section 4 Staircase Labs

I realize that this lab was supposed to be an easy one, but in all labs you should show the equations you use in your discussions. Few of you did this. Also, you were meant to include KE in your calculations of power. Furthermore, while f dot distance is a definition of Work, it is almost always more instructive to use work causes change in  KE plus change in PE in complex situations such as this one. 

For these reasons, most of the labs were in the B range, and even that was generous.

However, in the spirit of making this a recreational lab, I will only count it if it helps your grade.
