Car A is traveling on a highway at a constant speed. Initial velocity A = 80 mi/h and is 380 ft from the entrance of an on-ramp when car B enters the acceleration lane at that point at a speedInitial speed B = 20.0 mi/h. Car B accelerates uniformly and enters the main traffic lane after traveling 290 ft in 3.3 s. It then continues to accelerate at the same rate until it reaches a speed of 80 mi/h, which it maintains. Determine the final distance between the two cars (in ft).
