In Figure (a), a 3.1 kg dog stands on a 18 kg flatboat at a distance D = 8.2 m from the shore. He walks 1.2 m along the boat toward shore and then stops. Assuming no friction between the boat and the water, find how far the dog is then from the shore. (Hint: See Figure (b). The dog moves leftward and the boat moves rightward, but does the center of mass of the boat + dog system move?) (a) Dog's displacement da Boat's displacement d, (b) Number Units
