An excursion train, travelling at 80ft/s, encounters a rain shower. The point A lies directly 8ft. beneath the lip of an overhang in the observation car. The raindrops can be assumed to be falling at a constant speed of 40ft/s. Under the current conditions, a raindrop just clearing the lip would strike the observation car's floor 16ft from the point A. At what constant rate would the train need to be decelerating ( deceleration starting just as the drop passes the lip) for the drop to hit the floor 8ft. from A? What angle does the raindrop's velocity vector make with respect to the floor at the time of impact, as seen by an observer on the train?
