Homework Statement
A spring with spring constant 35N/m is attached to the ceiling, and a radius=0.025m, 1.0kg metal cylinder is attached to the lower end. The cylinder is held so that the spring is neither stretched nor compressed, then a tank of water is placed under-neath with the surface of the water just touching the bottom of the cylinder. When released, the cylinder will oscillate a few times but, damped by water, reach an equilibrium position. When in equilibrium, what length of the cylinder is submerged?
Homework Equations
Fspring=-kx
Vcylinder=∏r^2h
Fb=rho*Vfluid*g
THe answer is given, (18.1cm) but I'm kinda confused as to how the solution came about
The Attempt at a Solution
Fnet=Fb-(Fg+Fspring)
rho*Vfluid*g =mg+ kx ?
Help/hints much appreciated!
