If he throws the ball forward it will go forwards. If the train is traveling at 50mph, then everything on the train is also travelling at 50mph - the man, the air inside it, and the ball. If the man throws the ball at 5mph (essentially he gives it 5mph more forward momentum) it will travel forwards at 5mph for those on the train, and at 55mph for those who are stationary outside the train.

If he threw it out of the window it would fall behind him, because the wind resistance would immediately slow the ball down - while he continues to travel at his constant 50mph. However, for the observer outside the train it would still travel forwards, although slower than 50mph.

If he had the windows wide open then the air on the train wouldn't be travelling at 50mph (that is why it's windy when you open the window), the ball would still travel forward, but if he threw it at 5mph it would slow down faster than it would if the air was still, because of the air resistance.

It depends on how far away the ground is. When he first throws it, it WILL go forward from his hand. Just like a missle leaving a jet fighter... it takes both the speed of the train, and the velocity o the throw. However, as soon as it leaves the hand, it is pushed back by the rushing air. SO.... if the ground was close, it might hit that ground before being pushed back much. but if the ground is 10 feet below, you throw the ball and then the wind from the high speed of the train will get it, and push it back.

Think of sticking your hand out the indow of a speeding car...thats the wind that pushes the ball.

Why not take a ball out in a car and try it for yourself at varying speeds?

if a man is sitting in a train moving with constant velocity throws a ball and when he throws the ball. the ball will just fall down and will move a little at the back due to the speed of the train.

If he throws it upward, it will fall back into his hand. It's all about relative motion. The man and the ball are moving at the same velocity as the train, so treat the situation as if he were not even on the train.

If he throws the ball outside the train, it will be pushed back by the wind. If inside, it will depend on the velocity used to throw the ball, but it will be normal (like throwing a ball outside of a train).

depends...
where does throw the ball
if he throws it in front it will fall in front and similarly if he throws it behind him it will fall behind him
this is so because the ball,as it is in the train, is moving with the same velocity as that of the train

If he throws it in the train, it will land on his hand (unless he's throwing it away). The ball is traveling at that same constant velocity.

Behind if he is pitching for the Orioles
Dont throw a ball inside a train you moron you may hit someone.

It all depends on which direction he is throwing in & at which speed he is throing relative to the speed at which he is moving.

If thrown upwards: more chances of it landing behind him, since while the ball is moving upwards he would have moved in front of his previous position.

IF thrown infront: It will land in front, but again depends on his relative speed.

Hope this answers yr question.

If it fall in the train, it will be at front. if it fall outer area of train it will fall on behind him due to opposite reaction/air force/speed of train
