Solution
The correct option is D Fall either ahead or behind the thrower
Since the train is moving with non-uniform velocity, it means the train is either accelerating or retarding.
Thus, there are two possible conditions:
1. Train is accelerating: The tossed coin moves forward with the same velocity as that of the velocity it possessed when it was tossed. But the train is accelerating along with the thrower. Thus, the thrower moves forward but the coin falls behind the thrower.
2. Train is retarding: Similarly, as explained above, if the train is retarding the coin falls ahead of the thrower.
Hence, the correct answer is option (4).
