You are standing on Alumni field and watch 2 cars going down the PCH which has an incline of 12 degrees to the horizontal. The first car is toward the bottom of the hill, it is stopped at the light and is 24m ahead of the second car. The second car starts to skid. The second car has an initial speed of 18m/s when the first car is 24m ahead at the beginning of the skid. a) If the road has a dry surface, the coefficient of friction between the tires and the road is 0.6, what speed does the second car hit the first car? b) If the road has a wet surface, the coefficient of friction between the road and the tires is 0.1, what is the speed the second car hits the first car?
