Question

A man sitting in a train in motion is facing the engine. He tosses a coin up, the coin falls behind him. The train is moving:

• A. forward with uniform speed
• B. backward with uniform speed
• C. forward with acceleration
• D. forward with retardation

Answer 1

The correct option is C

forward with acceleration

1. The man sitting in the moving train is also in motion with the train.
2. This means the man is moving with the same velocity as that of the train.
3. when the man tosses a coin if the speed of the train is uniform, the coin will land in the hand of the man due to inertia of motion.
4. But if the train is accelerating then due to acceleration the velocity of the train increases along the direction of motion.
5. And at this time when a coin is tossed it does not fall in the hand of the man, it falls behind.
6. As the train comes in accelerated motion in forward direction as soon as it is accelerated but at the same time the coin does not get accelerated and it falls behind.

Thus,

option c) forward with acceleration is the correct option.
