On Mercury, the acceleration due to gravity is 3.59 m/s2. How far would a 45 g rock fall from rest in 5.5 seconds if the only force acting on it was the gravitational force due to Mercury? Answer in m.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
