Calculate the work required to lift a 5−m chain over the side of a building. Assume that the chain has a density of 8 kg/m. Use g=9.8 m/s^2

Hint: Break up the chain into N segments, estimate the work performed on a segment, and compute the limit as N→∞ as an integral. The small segment of the chain of length Δy located y m from the top is lifted through a vertical distance y. (Use decimal notation. Give your answer to one decimal place.)
