Homework Statement
A solid wooden cylinder of radius r and mass M. It's weighted at one end so that it floats upright in calm seawater, having density ρ the buoy is pulled down a distance x from it's equilibrium position and released.
a- Show that the block will undergo s.h.m
b- Determine the period of oscillations (the resistive effects of water are ignored)
The Attempt at a Solution
F=W-Fb
g/ρ(ρ-ρw)=a
I was trying to get a=-w^2 x
