This is not a question from a textbook, I am just supposing a situation. A book is lying on a table with some friction. If I push on the book, the book will push on me with an equal and opposite force; the book will then push on the table with friction, and, in return it, the table will push with an equal and opposite force on the book. How does then book move then? I push with a force on the book, the force is transmitted into the book, and it pushes on the table that has friction, and the table pushes back with an equal force. Doesn't, then, the friction force equal the force that I push with?
