If a boat is being tugged by 2 tug boats 20000 newtons north, the river is flowing at 5000 newtons south what direction is the boat and what's the velocity?
To determine the direction and velocity of the boat, we need to calculate the net force acting on the boat. The net force is the vector sum of all the forces acting on an object.
In this case, we have two tug boats tugging the boat northward with a force of 20,000 newtons each. Since both tugs are pulling in the same direction, we can add their forces together to get a total force of 40,000 newtons north.
We also have the river flowing southward with a force of 5,000 newtons. Since this force is acting in the opposite direction, we subtract it from the force exerted by the tug boats. The net force on the boat is 40,000 newtons (from the tug boats) minus 5,000 newtons (from the river), which gives us a net force of 35,000 newtons north.
Now, let's determine the direction of the boat. Since the net force is acting in the north direction, we can conclude that the boat is moving north.
The velocity of the boat can be calculated using Newton's second law, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration. However, we don't have information about the mass of the boat or any other factors that would directly allow us to calculate the acceleration. Therefore, we cannot provide a specific value for the velocity of the boat.
