    Question

    If a boy sitting in a train, which is moving at a

    constant velocity, throws a ball straight up into the air, the ball will –
    A Fall in front of him Correct Answer Incorrect Answer
    B Fall behind him Correct Answer Incorrect Answer
    C Fall into his hand Correct Answer Incorrect Answer
    D None of the above Correct Answer Incorrect Answer

    Solution

    If a person throws a ball vertically upwards in a moving train, it comes hack to his hand. The moment the ball was thrown, the ball was also in motion alone with the person who had thrown the ball and the train. This is due to inertia of motion. So when the ball remains in the air, both the person and the ball move ahead by the same distance. This makes the ball to come back to his hand on its return.
