Three dogs pull a sled that has a mass of 215 kg. If the coefficient of kinetic friction between the sled and the snow is 0.11, what force would the dogs need to pull to keep the sled moving at a constant velocity? (Hint: Consider what the net force would need to be if moving at a constant velocity)

The net force is the vector sum of all the forces acting on an object. When an object is in equilibrium (either at rest or moving with constant velocity), the net force acting on it zero. A vector can only have zero magnitude if all of its components are zero.
