The coefficient of kinetic friction between tires and dry pavement is about 0. 80 . Assume that

Question:

The coefficient of kinetic friction between tires and dry pavement is about 0. 80 . Assume that while traveling at $27 \mathrm{~m} / \mathrm{s}$ you lock your brakes and as a result the only horizontal force on the car is the frictional one.

(a) How many seconds does it take you to bring your car to a stop?

(b) If the road is wet and the coefficient of kinetic friction between tires and pavement is only 0.25 , how long does it take?

(c) How far do you travel in this time interval?
