If a 100ib women walks up a flight of stairs to get to the top of a 100 meter building. how much work did she perform?

Given that

force ( F) = 100 lb ,

displacement (S) = 100 m ,

Determine , Work = ?

                     Work = Force × displacement

                           W = 100 ×  100

                           W = 100000 lb-m

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).
