1. The problem statement, all variables and given/known data 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? 2. Relevant 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 3. The attempt at a solution Fnet=Fb-(Fg+Fspring) rho*Vfluid*g =mg+ kx ? Help/hints much appreciated!
