# Floating boat

Classical Mechanics Level 2

Two boats $$A$$ and $$B,$$ connected with a string, are floating on a calm lake. The mass of $$A$$ and $$B$$ are $$100 \text{ kg}$$ and $$150 \text{ kg},$$ respectively, and the distance between them is $$25 \text{ m}.$$ If the string is pulled from boat $$A$$ with a constant force and the two boats meet in $$20 \text{ seconds},$$ what is the distance that boat A moves?

Suppose that there is no friction whatsoever.
