Hello,
I have a problem that I thought I knew how to figure out but I'm getting a bit stuck. Here's the problem:
A 0.82kg block is hung from and stretches a spring that is attached to the ceiling. A second block is attached to the first one, and the amount that the spring stretches from unstrained length increases by a factor of 8. What is the mass of the second block?
My problem is that there isn't a spring constant given here.
I would guess that once the second block has been added, the two blocks aren't going up and down or oscillating. So that would make this problem an equilibrium one.
In that case I know that F = W ------ F = kx and W = mg
I's assuming that x is 8 but that doesn't make sense to me since that isn't 8 really isn't a distance. At least I don't think it is...
Anyway, I'm just lost..Any help would be greatly appreciated.
