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?”

Question

Expert Solution

Step 1

From the diagram, we can clearly see that the force F is at an angle 50 (30+20) degrees from the plane.

Step 2

Hence, we can indicate all the forces acting on the block using the free body diagram as below.

Here, N is the normal force perpendicular to the surface

mg is the weight of the block
