Find the work done in winding up a 300ft cable that weighs 2.00 lb /ft
W=Fd
W=$$\int F dx$$
My attempt
w=F*D
so W= (300ft)(2.00lb/ft)
W=600ft.lb
and
$$\int_0^{300}\!\ 2xdx$$
W=90,000 ft.lb
I'm taking Calc 2 and this is applied Physics problems.
Which of these answers is correct?
And Why?
Thanks in advance
Cheers!
