Question
When a man jumps from a boat to the shore, the boat moves away from the shore. Why?
Solution
When a man jumps from a boat to the shore, the boat slightly moves away from the shore.
This is due to the reason that when man jumps from boat, the man gets the momentum in forward direction and to conserve the momentum of system (man+boat) the momentum of boat should be equal and opposite to that of man.
