Adog sledding team is composed of a 81.8 kg musher (the person driving the sled), a 21.2 kg sled, and four dogs. assume that each dog's pull is fully transmitted to the sled, applied parallel to the ground, and the sled travels along level ground. how much power does each dog supply to pull the sled and driver system at a constant speed of 9.20 m/s if the coefficient of friction between the sled and the snow is 0.110? the acceleration due to gravity is 9.81 m/s².
