Two cars traveling toward each other on a single lane road at 16 m/s and 12m/s respectively when 120m apart both drivers realize the situation and apply their brakes. They succeed in stopping simultaneously and just short of colliding. Assuming a constant deceleration of each car, determine (a) time required for the car to stop (b) the deceleration of each car (c) the distance traveled by each car while slowing down.

Two cars are traveling in the same lane in the same direction. They are 120 ft apart and are both traveling at 60 mph. The roadway is level. The leading car hits a disabled milk truck and comes to an instatenous stop. The perception-reaction time of the driver in the trailing car is ½ second. The driver of the trailing car locks the brakes and skids into the lead car. The coefficient of friction between the roadway and skidding tires...
