What is the difference when a plane and a bullet enter water?

When a plane enters water, it typically experiences significant drag and deceleration due to its larger size and slower speed, resulting in a more controlled but potentially destructive impact. In contrast, a bullet, traveling at much higher speeds, penetrates the water more easily, creating a smaller entry hole and less drag relative to its speed, allowing it to travel further underwater before slowing down significantly. The physics behind both scenariOS involves differences in velocity, mass, and surface area, leading to distinct behaviors upon entry.
