Question

How can I calculate the buoyant force of the boat ?

Answer 1

Hint:-
 The buoyant force can be calculated with the equation
$$F_b=V_s\times D\times g$$

Complete step by step solution:
In general teams, this buoyant force can be calculated with equation

$$F_b=V_s\times D\times g$$

where ,
fb - Is the buoyant force that is acting on the object.
Vs = submerged volume of the object.
D = Density of fluid the object is Submerged in.
G =force of gravity.
Measure the distance you walked down the boat.
The weight of boat times the distance it moved, equal is your weight times the distance you moved.
The principle of the conservation of momentum is what makes this work:
Archimedes principle state the upward buoyant farce that is exerted on a body immersed in a fluid whether fully or partially submerged, is equal to the weight of the fluid that body displaces and its acts in upward direction at the center of mass of the displaced fluid so you must calculate the volume of the boat of immersed in the fluid and multiply by the specific weight of the fluid:
$$F=v\times {\displaystyle \frac{f}{v}}=v\times g\times {\displaystyle \frac{m}{v}}$$

Note: Buoyant force is equal to the volume of liquid multiplied by density and multiplied by the gravitational force. A body floats in water with 70% el volume inside the water.
  $$\text{buoyant force}={\displaystyle \frac{\text{weight of object in water}}{\text{weight of object in air}}}$$
