A bucket that weighs 3.4 pounds and a rope of negligible weight are
used to draw water from a well that is 81 feet deep. The bucket is
filled with 43 pounds of water and is pulled up at a rate of 3 feet
per second, but water leaks out of a hole in the bucket at a rate of
0.15 pounds per second. Find the work done pulling the bucket to the
top of the well. Your answer must include the correct
units. (You may enter
lbf or
