Two groups of canoeists meet in the middle of a lake. After a brief visit, a person in canoe 1 pushes on canoe 2 to separate the canoes. Suppose the speeds of the two canoes after they are pushed apart are 0.65 m/s for canoe 1 and 0.47 m/s for canoe 2. If the mass of canoe 1 is 270 kg , what is the mass of canoe 2?
