A man whose mass is 85 kg and a woman whose mass is 50 kg sit at opposite ends of a canoe 5 m long, whose mass is 45 kg. Assume the man is seated at x = 0 and the boat extends along the positive x axis with the woman at the other end. Suppose that the man moves quickly to the center of the canoe and sits down there, while the woman moves quickly 1/3 the length of the canoe towards the man. How far does the canoe move in the water? Assume force of friction between water and the canoe is negligible.
