The boat moves backward when the person jumps out of the boat is due to the reaction force of the person on the boat in the backward direction.
Explanation:
The direction of the reaction force acting on a body due to the action of a force in a particular direction is given by the Newton's law.
According to Newton's third law, every action has its equal and opposite reaction. This means that there is a reaction for every force acting on a body. The magnitude of the reaction is same as that of the action but it acts in the opposite direction.
When the person jumps out of the boat to a pier, the person pushes himself in the forward direction to move out of the boat. While doing this, the person also applies a reaction force on the boat in the the backward direction.
Due to this reaction of the person on the boat, the boat moves in the backward direction whereas the person jumps out of the boat to a pier.
Thus, The boat moves backward when the person jumps out of the boat is due to the reaction force of the person on the boat in the backward direction.
