A piece of wood of density = 0.5 3 and height = 50 was floating on the surface of water of density = 1 3 . After applied force additionally submerged this piece of wood on depth h and then removed, wood started bobbing. Derive equation of these vibrations similar to spring-box oscillations ( = 0) and define A piece of wood of density = 0.5 3 and height = 50 was floating on the surface of water of density = 1 3 . After applied force additionally submerged this piece of wood on depth h and then removed, wood started bobbing. Derive equation of these vibrations similar to spring-box oscillations ( = 0) and define bobbing period T . Present equation for wood instantaneous depth of submersion
