SUMMARY
The discussion centers on calculating the distance a boat moves when a boy shifts his position from the stern to the bow. Given the mass of the boat (M=80kg) and the boy (m=36kg), the principle of conservation of momentum is applied, leading to the equation M_{boat} \Delta {X_{boat}} + m_{boy}\Delta {X_{boy}} = 0. By establishing a reference frame at the bow of the boat, the displacement of the boat can be calculated using the relationship between the boy's displacement and the boat's length (2.8m).
