Homework Statement


A leaky 12 lb bucket is lifted from the bottom of a 10 ft well to the top at
a constant speed with a rope that weighs 0.6 lb/ft. Initially the bucket contains 60 lb
of water but the water leaks at a constant rate and finishes draining just as the bucket
reaches the top of the well. How much work is done?


Homework Equations


w = \int_{a}^{b} [F(x)]dx


The Attempt at a Solution


w = \int_{a}^{b} [F(x)]dx

w = \int_{0}^{10} [0.6(10 - x) + 6(10 - x)]dx

w = 330 lb-ft


Is this correct?

Don't forget the weight of the bucket. :wink:
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
