I am working on a lab and I'm not sure how to calculate the work (done by me). I know work = W=(F Cos theta) and Force =F= W/t In the lab I am to walk up a set of stairs and time myself. I did this and got the following: t=8 sec d=6m Mass(me)= 77kg how do I find W? Any pointer is greatly appreciated. I know I'm making this harder than it has to be I'm sure.
