A man with a mass of 70 kg is out fishing with his daughter, who has a mass of 30 kg. They are initially sitting at opposite ends of their 3.0-m boat, which has a mass of 60 kg and is at rest in the middle of a calm lake. If the man and the daughter then carefully trade places, how far does the boat move (relative to a fish who is hiding motionless underneath the boat)?
