Question

a passenger in a moving train tosses a coin which falled behind him is the motion of the train is retarded or accelerated?​

Answer 1

If the coin falls behind the passenger that means the train is accelerated. When the coin is tossed it has same velocity as that of train but during the time it is in air its velocity becomes less than that of train (because the train is accelerated), so it falls behind the passenger.
