Richard, mass 78.4 kg, and Judy, who is less massive, are en- joying Lake George at dusk in a 31.6-kg canoe. When the canoe is at rest in the placid water, they change seats, which are 2.93 m apart and symmetrically located with respect to the canoe's center. Richard notices that the canoe moved 41.2 cm relative to a submerged log and calculates Judy's mass. What is it?
