Path of an object

If a man tossed a coin in a moving train and the coin fell back . Then in which type of motion train is moving? and how?

CHANDRIMA

Answer

For the person who tosses the coin the motion is vertically upward if he do so. But for an observer outside the train the path of the stone is a parabola.This is due to the horizontal velocity of the stone.

If the stone fell back, it means that the train is accelerated. If it were moving with a constant velocity, then the stone would’ve reached back to his hands only as both the train and the stone possess the same horizontal velocity.
