A horizontal force of 12 N pushes a 0.50-kg book against a vertical wall.The book is initially at rest.If = 0.60 and = 0.50, the acceleration of the book is: A)0 m/s² B)9.4 m/s² C)9.8 m/s² D)14.4 m/s² E)19.2 m/s²

Since the horizontal force is used to push the book against the wall, it does not contribute to the book's acceleration in the horizontal direction. The only forces acting on the book in the vertical direction are its weight and the normal force from the wall, which balance each other out. Therefore, there is no net force to cause acceleration, meaning the book remains at rest or moves at a constant velocity if it was already in motion. The coefficients of static and kinetic friction provided are not relevant to the calculation of acceleration in this context.
