Great video ! For those of you that are solving for work make sure when you calculate force you multiply the mass by 9.80 m/s^2 for the correct answer.
Because the calculation is done in terms of pounds instead of kilograms, and pounds is already a unit of force comparable to newtons, 9.8 m/s^2 does not need to be multiplied.
'g' is part of pounds already since pounds are English force units not mass units. If this was given in SI measurements then you would be correct to multiply by 'g' to get our force units to determine work.

I have a couple of calculus texts that don't go anywhere near the detail I find in this great video. Sir, I doff my hat to you! Bravo and thank you!
Great video! Explains the problem very well and very efficiently. Thanks you just saved my from missing that problem on my homework.
Absolutely excellent explanation. Very in depth. Much appreciated.
This helped! I wasn't t seeing the connection with the circle function and final integral. Thanks for your time.
Solution nicely detailed, however, it looks like you are explaining while still in bed, hahaha... Thanks a lot for sharing.
I was searching for a long time this case of work to pump liquid, thanks
Thank you!! This is the exact problem in my homework today!!
Super helpful. Thank you.
That was very helpful!
thanks, this is a refresh vid
what if the tank is full?
My mans recorded this in bed lmao. Great explanation though.
WHAT IF THERE'S NO GIVEN DENSITY OF WATER? what i will do
I think force should equals density times volume times g.
'g' is part of pounds already since pounds are English force units not mass units. If this was given in SI measurements then you would be correct to multiply by 'g' to get our force units to determine work.
The English/imperial system is such an awkward system with which to work.
Limit of integration should be from -2 to 3
