Math Problem Statement
Peyton is using a rope to lift a bucket from the bottom of a 25-foot-deep well. The rope weighs 0.6 lbs/ft. The bucket (by itself) weighs 3 lbs and is initially holding 3 lbs of water. Unfortunately, Peyton is lifting this bucket in the middle of a torrential downpour. By the time the bucket reaches the top of the well, it contains 8 lbs of water.
Assuming she lifted the bucket at a constant rate and the rain is filling the bucket at a constant rate, set up, but do not evaluate, an integral to represent the work Peyton did in lifting this bucket.
