A fisherman in a boat catches a shark with a harpoon. The shark struggles for a while and then becomes limp when at a distance of 300 m from the boat. The fisherman pulls the shark all the way to the boat by the rope attached to the harpoon. During this operation, the boat (initially at rest) moves 45 m in the direction of the shark. The mass of the boat is 5400 kg. What is the mass of the shark? Pretend that the water exerts no friction. (Hint: Friction is ignored, so there are no external forces, and the center of mass of the system (the shark and boat) should not move at all.) A) 953 kg B) 477 kg C) 318 kg
