Two persons of masses $55\, kg$ and $65\, kg$ respectively, are at the opposite ends of a boat. The length of the boat is $30\,. m$ and weighs $100\, kg$. The $55\, kg$ man walks up to the $65\, kg$ man and sits with him. If the boat is in still water the center of mass of the system shift by:
- 3.0 m
- 2.3 m
- Zero
- 0.75 m
