Car A is traveling at 65 km/h when it enters a 50 km/h speed zone. The driver of car A decelerates at a rate of 20 m/s2 until reaching a speed of 50 km/h, which she then maintains. When car B, which was initially 20 m behind car A and traveling at a constant speed of 70 km/h, enters the speed zone, its driver decelerates at a rate of 25 m/s2 until reaching a speed of 48 km/h. Knowing that the driver of car B maintains a speed of 48 km/h, determine a) the closest that car B comes to ca A, b) the time at which car A is 25 m in front of car B.

Car A is traveling on a highway at a constant speed (VA)0 = 60 mi/h and is 380 ft from the entrance of an access ramp when car B enters the acceleration lane at that point at a speed (VB)0 = 15 mi/h. Car B accelerates uniformly and enters the main traffic lane after traveling 200 ft in 5 s. It then continues to accelerate at the same rate until it reaches a speed of 60 mi/h, which it then maintains. Determine the final distance between the two cars.
