1. The problem statement, all variables and given/known data
Problem with picture attached
I need help on 24. **24 is a continuation of 23 so use the same dimension except for the distance...
Or you can go here http://college.cengage.com/mathemati...SECT=a&TYPE=se
Chapter 7, Lesson 5
2. Relevant equations
Water= 9800 N/m^3
∫(Volume)(water)(distance)=Work done ??
3. The attempt at a solution
Distance is where I'm not too sure about. Would I use (10-y)??
If so then I got...
∫9800*4∏Δy*(10-y), from 0 to 4 = 1,254,400∏ N-m
My answer looks really huge... Did I mess up anywhere?
