A 5.0-kg penguin sits on a 10-kg sled, as shown in the figure. A horizontal force of 45 N is applied to the sled, but the penguin attempts to impede the motion by holding onto a cord attached to a wall. The coefficient of kinetic friction between the sled and the snow, as well as that between the sled and the penguin, is 0.20. a. Draw a free-body diagram for the penguin and one for the sled, and identify the reaction force for each force you include. b. Determine the tension in the cord. c. Determine the acceleration of the sled.

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?”
