Im having trouble with this problem. I know that KE=1/2mv^2 and the Wrok engergy theorm W=KFf-KEo but I am having trouble relating the figure to KE.
Two boxes are connected to each other as show. The system is released from rest and the 1.00 kg box falls 1.00 m. The surface of the table is frictionless. What is the KE of the box before it reaches the floor?

EDIT-
I was looking itover and I think I kind of know what to do...
I need to find KEf.
KEf=W+KEo
and to find W, W=(F cos 180) s
is that on the right track?
