Romeo (77.0kg) entertains Juliet (55.0 kg) by playing his guitar from the rear of their boat at rest in still water, 2.70m away from Juliet, who is in the front of the boat. After the serenade, Juliet carefully moves to the rear of the boat (away from the shore) to plant a kiss on Romeo's cheek. How far does the 80.0kg boat move toward the shore it is facing?
