A dog sledding team is composed of a 80.8 kg musher (the person driving the sled), a 23.0 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 9.10 m/s if the coefficient of friction between the sled and the snow is 0.140? The acceleration due to gravity is 9.81 m/s2.

A dogsled team has four dogs that pull a person and a sled with a combined mass of 100 kg. a) They start from rest and reach a speed of 45 km/h in 2.5 s. What is the net force applied by each dog? Hint: you need to convert 45 km/h to m/s first! b) Suppose each dog can pull with a force of magnitude 150 N. What is the frictional force acting on the sled? Please type in main...

Six dogs pull a two-person sled with a total mass of 220 kg. The coefficient of kinetic friction between the sled and the snow is 0.080. The sled accelerates at 0.75 m/s2 until it reaches a cruising speed of 11 km/h. part A) What is the team's maximum power output during the acceleration phase? part B) What is the team's power output during the cruising phase?
