A horse is harnessed to a sled having a mass of 236 kg, including supplies. The horse must exert a force exceeding 1 240 N at an angle of 35.0o in order to get the sled moving. Treat the sled as a point particle, (a) Calculate the normal force is 1 240 N. (b) and the coefficient of static friction between sled and the ground beneath it. (c) Find the static frirction force when the horse is exerting a  force of 6.20×102 N on the sled at the same angle.

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?”
