A drag racer crosses the finish line of a 304.8 m track with a final speed of 121 m/s.

(a) Assuming constant acceleration during the race, find the racer's time and the minimum coefficient of static friction between the tires and the road.

time 1 s

minimum coefficient of friction 2

(b) If, because of bad tires or wet pavement, the acceleration were 31.1% smaller, how long would it take to finish the race?

3 s
