Displacement of the ship carrying. The displacement of a ship carrying 4000 tons of cargo at a draft

Displacement of the ship carrying. The displacement of a ship carrying 4000 tons of cargo at a draft of up to the waterline is 6 * 10 ^ 4 kN. What is the mass of the ship itself?

To find the mass of the ship under consideration, we will use the formula: mk = m – mg = P / g – mg.

Constants and variables: P – displacement of the specified ship; the force of gravity acting on the cargo and the vessel (P = 6 * 10 ^ 4 kN = 6 * 10 ^ 7 N); g – acceleration due to gravity (g ≈ 10 m / s2); mg is the mass of the cargo (mg = 4000 t = 4 * 10 ^ 6 kg).

Let’s make a calculation: mk = P / g – mg = (6 * 10 ^ 7) / 10 – 4 * 10 ^ 6 = 2 * 10 ^ 6 kg.

Answer: The own mass of the ship in question is 2 * 10 ^ 6 kg.
