Homework Statement
Two forces act on an object of mass 2.5kg; force F1 that is directed alont the +x-direction and has magnitude of .50N and force F2 that points at a 45 degree angle in the +y and -x quadrant and has magnitude 2.0N. Find the additional force, if any such that the object will...
the first number in the integral is the upper bound and the second is the lower... I just can't get it to be formatted the right way for some reason.
EDIT: sry about the repeat... said database error so I thought it didn't go through.
EDIT: OMG there's 2 double posts... srry

The Attempt at a Solution
line x=3: 2/pi/int(3-x)(2x+3)dx =115.19
answer key is unfortunately in disk method which I don't like as much:
\pi\int^{3}_{0}(9-4)dy + \pi\int^{5}_{3}(3-((y-3)/2))^{2}-4dy
=78.91
line y=5...

Homework Statement
Find the volume of the solid of revolution:
F(x)=2x+3 on [0,1]
Revolved over the line x=3 and y=5
Homework Equations
Shell Method: 2\pi\int^{b}_{a}x[f(x)-g(x)]dx
obviously just sub y for dy
Disk Method...
