Two people are on a row boat on the river. The current of the river water carries them at a speed of 5 m/s. Even when they are not rowing what will happen to the boats motion if no other forces act on the boat, the boat speed will increase the boat speed will decrease the boat speed will stay the same or the boat will change direction.
If no other forces act on the boat, the boat speed will stay the same.
If no other forces act on the boat, the boat speed will stay the same. The current of the river water carries them at a constant speed of 5 m/s, so even if they are not rowing, the boat will continue to move with the same speed as the current.
In order to determine what will happen to the boat's motion, we need to consider the forces acting on the boat. In this scenario, the only force mentioned is the current of the river.
When the boat is not rowing, the only force acting on it is the current of the river water. Since the current carries the boat at a speed of 5 m/s, we can conclude that the boat speed will stay the same.
Since no other forces are mentioned, there is no reason for the boat speed to increase or decrease. Additionally, since there is no mention of any force causing the boat to change direction, we can assume that the boat's direction will remain the same as well.
Therefore, the boat's speed will stay the same and the boat will continue to move in the same direction as the current.
