(a) If the coefficient of kinetic friction between tires and dry pavement is 0.82, what is the shortest distance in which you can stop an automobile by locking the brakes when traveling at 26.6 m/s (about 60 mi/h)?

(b) On wet pavement the coefficient of kinetic friction may be only 0.27. How fast should you drive on wet pavement in order to be able to stop in the same distance as in part (a)? (Note: Locking the brakes is not the safest way to stop.)
