Why when a ball thrown vertically upwards by a man in a moving train comes back to his hand?

that depends on 3 factors, how big is the circle, how fast is the train, and how high is the ball thrown
also it is to be considered that u are assuming the natural (actual) conditions like the air thrust is present or hypothetical conditions that there is no air thrust.
Under all ideal conditions i.e. no air thrust etc. the ball will move tangentially to the path of the circle the train is traversing.

The man on the moving train is moving forward, and so is the ball in his hand before he throws it. After the man throws it up, he puts an external force on it to go up, but no forward/back force on it. Gravity then puts an external force on the ball, and brings it back down, but gravity does not have any forward/back force. So the ball will continue forward at the same forward velocity as the man's hand.
(of course if there is air resistance, that is an external forward/backwards force, but I am assuming that there is none).

∙ 15y agowell i guess it depends if the car is moving :/

If a moving bodycomes to restthen its acceleration is-?
To come to rest, its velocity must change, therefore it will accelerate. Once it is at rest, if it remains at rest, it will no longer accelerate, i.e., its acceleration will be zero.

What happens to the speed of an object when it is thrown up in the air and when it comes back down?
an object thrown into the air will slow down as it ascends higher into the air until it stops ascending and the speed of the object increases as it falls until it reaches its terminal velocity in air. As an object passes through air, it encounters air resistance which slows down an object moving freely through air. An object will be moving at a slower speed when it hits the ground than it did when it was thrown into the air due to this air resistance.
What happened to the ball when you thrown upward?
It comes back downward! :) enjoi!
Why it is taken as negative when an object is thrown upwards against gravitation?
When we throw the object upwards we consider that upward direction as positive. Therefore, the velocity in that direction is positive but the acceleration due to gravity is in the opposite direction and so it is considered negative. But when the ball comes down again after reaching a certain height the velocity is in opposite direction to the earlier one and so the velocity now is negative as a result the acceleration is again negative.

What is the name of the rocket launcher that shoots straight up in the air and comes down vertically on a target?
The rocket launcher that shoots straight up in the air and comes down vertically on a enemy or target is called a Javelin.

Ive heard the Playstation 2 can be kept vertically or horizontally is this true?
Yes, all models of the Playstation 2 can be set vertically or horizontally. The system comes with a stand to help keep the system vertical. Do not turn the console horizontally to vertically while the disc is spinning or it may get scratched.
A ball is thrown upward and caught when it comes back down In the presence of air resistance the speed with which it is caught is?
less than the speed it had when thrown upward.
What is Dynamic static?
