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?”

(Newton's laws and their applications) A block with mass m1 slides down an inclined plane whose angle is 22 °, the coefficient of kinetic friction between the block and the plane is 0,250. The block is attached to an ideal rope that passes through two ideal pulleys until it is attached to a fixed support, as shown in figure 3. A rope leaves the axis of the movable pulley up to a block of mass m2 3 m2 m1 Figure 3. Diagram of exercise 3 A. Discuss what difference the exercise will make if one more pulley is placed on the ceiling that makes the rope connect to the rod of the movable pulley.
