A 60 kg skier is in a tuck moving straight down a 30° slope. Air resistance pushes backwards on the skier with a force of 10 N (applied opposite the direction of the skiers motion and parallel to the 30° slope). The coefficient of dynamic friction between the skis and the snow is 0.08. What is the resultant force acting on the skier?

Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”
