A drag racer crosses the finish line of a 400 m track with a final
speed of 104 m/s. (a) Assuming constant acceleration during the
race, calculate the racer's time and the minimum coefficient of
static friction between the tires and the road. (b) If, because of
bad tires or wet pavement, the acceleration were 30 % smaller,
calculate how long it takes to finish the race.

7. Sally is driving at a constant speed of 25 m/s on a straight horizontal road. She sees an obstacle on the
road ahead and applies the brakes! The wheels lock causing the car to slide forward. If the coefficient of
kinetic friction between the tires and the road is 0.40, how long does it take the car to come to a complete
stop?
