A side-view diagram of a uniform canoe floating horizontally on a horizontal water surface. The canoe is drawn as a symmetrical elongated boat shape with slightly upturned ends, with an overall length indicated by a horizontal dimension arrow labeled 4.0 m and text inside labeled 40 kg. A figure representing a person labeled 60 kg stands at the left end of the canoe. A horizontal dashed line indicates the water surface level. No other labels, lines, text, or axes appear.
A person standing at one end of a canoe floating on calm water.
A person of mass \(60\text{ kg}\) stands at one end of a uniform canoe of mass \(40\text{ kg}\) and length \(4.0\text{ m}\) that is initially at rest on calm water. The person walks along the canoe to the opposite end and stops. Assuming drag and resistive forces between the canoe and the water are negligible, what is the magnitude of the displacement of the canoe relative to the water during this process?
