Question:

A car travels along a level road with speed v = 25 m/s (about 50 mi/h). The coefficient of kinetic friction between the tires and the pavement is µ_K = 0.55.

(a) If the driver applies the brakes and the tires “lock up” so that they skid along the road, how far does the car travel before it comes to a stop?

(b) If the same car is traveling downhill along a road that makes an angle θ = 12°, how much does the car’s stopping distance increase?
