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/s². 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?

A 2500kg car traveling to the north is slowed down uniformly from an initial velocity of 20m/s by a 6250 N braking force acting opposite the car's motion. (Hint: Since the force is going opposite of the car, then the force must be negative). How long does it take for the car to come to a complete stop? GU E SS
