Using the picture below, what must take place for the book to move in the direction of the movement arrow?
-A force must be applied to the top of the book to make sure that it is equal to the force of friction.
-The friction of the table must increase and the friction of the book decrease to allow for movement.
-The friction must be removed for any movement to take place.
-A force in the direction of the desired movement must be applied causing the forces to be unbalanced.
