Question 56





Why is the following situation impossible? Your -kg physics book is placed next to you on the horizontal seat of your car. The coefficient of static friction between the book and the seat is , and the coefficient of kinetic friction is 0.550. You are traveling forward at km/h and brake to a stop with constant acceleration over a distance of m. Your physics book remains on the seat rather than sliding forward onto the floor and vf =
