参考答案:
The ball will land on the roof of the railroadcar (ignoring air resistance and assuming that the velocity of the train isconstant). Both the ball and the car arealready moving forward, so when the ball is thrown straight up into the air with respect to the car, it will continue to move forward at the same rate as the car and fall back down to land on the roof.
