Final answer:
The net force can be found by multiplying the force exerted by each dog by the number of dogs and adding them up. In this case, the sled is being pulled to the left by 5 dogs, each dog pulling with 6 Newtons of force. Therefore, the net force is 30 Newtons to the left.
Step-by-step explanation:
The net force acting on an object can be found by adding up all the individual forces acting on it.
In this case, each of the 5 dogs is pulling with a force of 6 Newtons to the left.
The net force can be calculated by multiplying the force exerted by each dog by the number of dogs and adding them up.
Therefore, the net force is 5 dogs x 6 Newtons/dog = 30 Newtons to the left.
