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?
