An object floats on water if the buoyancy force of the water on the object is equal to the object’s weight. I.e. the buoyancy force makes things float. The buoyancy force on a ship that sits on the top of the water is 15,000 N. What is the mass of the ship?
"F=mg\\to m=F\/g=15000\/9.8=1531\\ (kg)" . Answer
