Solve the below problem:
Q: Car A is traveling on a highway at a constant speed (vA)0 = 100km/h and is 120 m from the entrance of an access ramp when car B enters the acceleration lane at that point at a speed (vB)0 = 25km/h. Car B accelerates uniformly and enters the main traffic lane after traveling 70 m in 5 s. It then continues to accelerate at the same rate until it reaches a speed of 100 km/h, which it then maintains. Determine the final distance between the twocars.
