A horseback rider is escaping from his pursuers. He sees a way out of his quandary in crossing a railroad before a long train reaches an intersection with the highway. At the moment he is 100 meters away while the train is 200 meters from the intersection and speeding at 75 km/hr. From his current speed of 20 km/hr what should his acceleration be if he succeeds to escape?
