2. Consider the following set of blocks being pulled across a rough horizontal surface by a constant force F. 3m 2m m 2m (a) Draw a FBD for each individual block, as well as for the system as a whole as they are being pulled by F. (b) Find the acceleration of each block, as well as the magnitude of each force acting on each of the blocks. Clearly show your work.

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?”
