A piece of wood with a density Pwood = 706 kg/m3 is tied with a string to the bottom of a water filled flask and is in equilibrium. The wood is completely immersed. The tension in the string is 0.89N. ( the density of water is Pwater=1.00 * 103 kg/m3 ).
a. Find the volume of the wood.
b. If the strings breaks, the wood starts moving upward due to the buoyancy force. Neglecting any viscous drag of water, determine the acceleration of the wood block at the time the string breaks.
c. After reaching the top of the surface, the wood block floats on the surface, does the water level in the flask rise, drop or stay the same?
d. Determine the fraction of wood's volume immersed while the wood floats on the surface of water
