You testify as an expert witness in a case involving an accident in which a car slides into a car that was stopped at a red light along a road headed down a hill. You find that the slope of the hill is è = 12 degree, that the cars were separated by a distance of 24.0 meter when the approaching car starts to slide, and that the speed of the car was 18.0 m/s when it started to slide. Your job is to find the speed of the car when it hits the car stopped at the light. Suppose the coefficient of kinetic friction between the tires and the road is 0.50.
