Question

this seems like a good place to start..

A 200-lb cable is 100 ft long and hangs vertically from the top of a tall building. How much work is required to lift the cable to the top of the building? Use integral calculus

Answer 1

well i think integral calculus will come into play when the weight of the cable is non-uniform i.e maybe function of distance..
otherwise this is a simple multipication problem as due to all terms constant,,integrating dosent come into play..

Answer 2

but it's in a calculus book o.O

Answer 3

here i have assumed speed of pulling to be constant..either make speed as a function of something..

Answer 4

Let, \( \lambda \) be your mass per unit length.
