With what force are 3 tons of oil attracted to the Earth? What is the mass of a concrete beam if it is attracted by the Earth with a force of 12 kN?
Fт = mass * gravitational acceleration = m * g
since g = 10m / s on the ground, and mass 3t = 3000kg, then
10m / s * 3000kg = 30000n = 30kN
According to the same formula, the mass of a concrete beam = Ft / g = 12000N / 10m / s = 1200kg
