Car A is traveling on a highway at a constant speed 0( ) 60mi/h, Av = and is 380 ft from the entrance of an access ramp when car B enters the acceleration lane at that point at a speed 0( ) 15mi/h, Bv = 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 60mi/h, which it then maintains. Determine the final distance between the two cars.
