Question

A light spring of constant k = 159 N/m rests vertically on the bottom of a large beaker of water (as seen in the picture below).
An m = 4.54 kg block of wood (density = 657 kg/m3) is connected to the spring and the mass-spring system is allowed to come to static equilibrium (b). What is the elongation, DeltaL, of the spring?

So I tried to find the buoyant force with this equation:
Fbuoyant = density of water * volume of block *g
And then I divided by the given value of k.
I ended up with .426 m but that was not correct.

Answer 1

can you give us the picture ?

Answer 2

One moment, let me try.

Answer 3

I had to take a screenshot, but there it is.

Answer 4

Thank you!
