Just like Louis, Maria left a book on the roof of her car before driving away. The mass of the book was 731 grams. The coefficient of static friction between the book and the roof was 0.29. The coefficient of kinetic friction between the book and the roof was 0.24. Maria started her car and drove forward on level ground with an acceleration of 3.5 m/s?. As Maria was driving away with that acceleration, what was the magnitude of the force of friction (in newtons) between the book and the roof of the car?
