A ship 60 m long and 10 m wide displaces 15000 kN of water. A weight of 200 KN is displaced across the deck through a distance of 5 m and the ship is tilted through 4.50. The moment of inertia of the ship about the fore - and - aft axis is 80% of the circumscribing rectangle. The centre of buoyancy is 2 m below the water surface. Determine the metacentric height and the position of the centre of gravity of the ship. Take specific gravity of water as 1.03.
