Question:
A hose that weighs 2.5 lbs per foot is being hoisted out of a 50-foot deep hole after filling an underground tank. One of the workers pulls out the first 20 feet of the hose out of the hole, and then another worker pulls the remaining 30 feet of hose out of the hole. How much work does each worker put into pulling the hose out of the hole? Set up a Riemann sum for the work done by the first worker, and use the same integrand for the work done by the second worker. The bounds will be different for each worker.
