Why is the following situation impossible? a freight train is lumbering along at a constant speed of m/s. behind the freight train on the same track is a passenger train traveling in the same direction at m/s. when the front of the passenger train is m from the back of the freight train, the engineer on the passenger train recognizes the danger and hits the brakes of his train, causing the train to move with acceleration . because of the engineer’s action, the trains do not collide.
