Keisha has two large dogs and a small dog. The dogs like to play tug-the-rope together. Each of these three diagrams shows one way that the dogs play together with the rope. Look at each arrow and the number that goes with it. They show the direction and amount of force each dog exerts on the rope. Look at the middle diagram, where the large dog and the small dog tug on the rope. Which statement correctly explains the amount and direction of the net force acting on the rope, and which direction the rope will move? *
