Complete Question:
A sailboat is moving at a constant velocity of 8 km/h eastward as shown in the picture below. Describe three forces acting on the boat. Explain how two of those forces affects the boat.
Answer:
The three forces acting on the sail boat is the forward force or the force with which the boat is moving, the frictional force or the resisting force by the water waves and the buoyant force acting on the body of the ship.
Explanation:
As the sailboat is moving with a velocity of 8 km/h towards east, then the pushing force is acting due to wind on the boat. So the wind is pushing the boat toward the east direction. But at the same time, the flow of water tides will provide a frictional or resisting force to the movement of ship.
So this resisting force by the tides on the sailboat is less compared to the force of the wind. So the boat is moving instead of collapsing. Similarly, another force acting on the boat will be the buoyant force.
This force will keep the boat on the surface of the water as a floating surface because of lesser density of boat compared to water. So the pushing force and the buoyant force helps in keeping the boat to be in motion and on surface of water.
