A car travels along a level road with a speed of 25m/s. The coefficient of kinetic friction between the tires and the pavement is 0.55.
a.) If the driver applies the brakes and the tires "lock up" so that they skid along the road, find how far does the car travel before it comes to a stop?
b.) Is the same car is traveling downhill along a road that makes an angle of 12o, find how much does the car's stopping distance increase?
c.) Determine the stopping distance on an uphill road with an angle of 12 degrees?
