1. The problem statement, all variables and given/known data A dog of mass 10.0kg is standing on a raft so that he is 20.0m from shore. He walks 8.00m along the raft towards shore and then halts. The raft has a mass of 40.0kg, and we can assume there is no friction between the raft and the water. How far is the dog from shore when he stops? 2. Relevant equations EK=1/2 mv2 3. The attempt at a solution This is a really tricky question and I'm not quite sure how to proceed. I know that when the dog halts, the raft moves forward towards the shore?
