The diagram shows a book that slides from left to right across a tabletop. Why are the forces balanced upward and downward but not balanced left and right?
The unbalanced force is directed in the same direction as the book's motion will cause it to decrease its speed

The unbalanced force is directed in the same direction as the book's motion and will cause it to increase its speed
The unbalanced force is directed in the opposite direction of the book's motion and will cause it to increase its speed
