1. The problem statement, all variables and given/known data A 55 kg man is standing on a 65 kg and 4.0 m length canoe that floats without friction on water. The man walks from a 0.75m from one end of the canoe to another point 0.75 from the other end of the canoe. What distance does the canoe move? 2. Relevant equations Center of mass equation. 3. The attempt at a solution A tried looking for the ΔXCM, the change on the center of mass, but I do not know how to compute the canoe's CM. Mod note: Fixed misspelling of "canoe."
