Answer 1

When the rope is fully extended (and all forces are in equilibrium), you have that the force gravity negates the force of the spring, right? I'm not as used to mechanics as I should be...

Answer 2

I'm not sure what you mean by negates the force of the spring..

Answer 3

I mean that one force plus the other is zero (hence in equilibrium).

Answer 4

i think so, yes.

Answer 5

Okay so if we set up that equation, we should be able to solve for the spring constant. I'm not entirely sure where the calculus comes into play though, sorry :/

Answer 6

it's alright, thanks anyway,
