# Frog jumping on a plank floating on water [closed]

I don't want you to give me the answer of the problem, I only whant to know how to think it.

A frog of 200g is sitting at the end of a plank of 1kg and 1 m of length. The plank is at rest and floating on the calm waters of a pond. Suddenly the frog jump along the board. If the frog falls at the other end of the plank, calculate the horizontal distance traveled by the frog. The friction between the board and the water is neglected and the frog can be considered as a point mass.

Because in fact I have an idea on how to solve it ,but I think the question is giving me the aswer in some way and I find it quite strange..beacuase it's an exam question ,and if that's the case it would be really easy.
