ok, let's say a bucket of water weighs 40 lbs. What, if any would the bucket weigh on a 20 ft rope?

Thx in advance.

my guess is 40lbs.

are you leaving out information?

[EDIT] technically this is a statics/dynamics question, not a math question.

The weight doesn't change (unless you mean it's now the weight of the bucket + the 20' of rope). The amount of force required to move the bucket may change if there's a pulley involved, but like Zartan said there's missing information if that's the case.

it depends on how the bucket is interacting with the rope and where the bucket is in relation to other things

uh....let's say the amont of force to raise the bucket. With/if there is a change how would that be expressed such as:

if it started at "1" and changed to"5" would it be like saying it was 200lb-I know that is not right but that's the idea of what I'm asking

you clearly don't even understand the question that you're asking.
how can you possibly evaluate a response accurately?

friar, sorry bud, but you are dumber than a $3 bill in Atlantic City.

if i took a 80lb bucket of jellyfish poop and hung it from a 40ft cable, it would be smarter than you.

Lifting a 40 lb bucket is like lifting X amount when it's on a 20 ft rope (with no pulley).
