A block is held at rest on an incline by a rope that is parallel to the incline as shown on the figure below. GKBOKBNDWAGWRONOURS Hint: you are almost guaranteed to get these questions wrong if you do not draw separate force diagrams for the block, one for parallel to the incline and the other for perpendicular to the incline. What is the newton's second law equation for the forces parallel to the incline? F's is the static friction force, W is the weight of the block, T is the tension in the string, N is the normal force, and is the angle of the incline. W sin 0 N W cos 0 = N W sin0 = Fs + T W cos 0 = Fs+T

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?”
