Please help me with this question ; in the image below **Physics Problem: Friction and Forces**3. Amy holds a 4-kg book against a wall by pushing on it exactly horizontally. The coefficient of static friction between the wall and the book is \( \mu_s = 0.28 \).a) **Task**: Draw a free body diagram for the book. *Hint: there are 4 forces acting on it.*- **Diagram Explanation**: - The forces typically involved would include: - The gravitational force acting downwards (Weight = mass \(\times\) gravity). - The normal force exerted by the wall, perpendicular to the surface. - The horizontal force applied by Amy. - The frictional force opposing the book's tendency to slide downwards.b) **Question**: How much force does Amy have to exert in order to keep the book from falling?c) **Scenario**: If Amy exerts only 90 N of force, the book will start to slide and continue to accelerate downward. If she manages to continue applying the 90 N constantly all the way down, and the coefficient of kinetic friction between the book and the wall is \( \mu_k = 0.20 \), at what rate will the book accelerate?
