Find the volume of the ice block on which the gravity force is 27 Newtons.

Ft = 27 N.

g = 10 m / s2.

ρ = 900 kg / m3.

V -?

The volume of the ice block V will be expressed by the ratio of the mass of this block m to the density of the substance ρ of which it consists: V = m / ρ.

The force of gravity Fт is called the force with which all objects located on its surface are attracted. The force of gravity Ft is determined by the formula: Ft = m * g, where m is the mass of the ice block, g is the acceleration of gravity.

m = Fт / g.

V = Fт / ρ * g.

The block consists of ice, according to the density table, its density is ρ = 900 kg / m3.

V = 27 N / 900 kg / m3 * 10 m / s2 = 0.003 m3 = 3 liters.

Answer: the block of ice has a volume of V = 0.003 m3 = 3 liters.
