Answer 1

Answer:

A. Accelerated

Hope it helps

Answer 2

It means the motion of the train is accelerated as the coins when thrown upwards is moving with the initial velocity of the train but now as the acceleration is increased, the coin is falling with the initial velocity of the train but the train gains it's speed. So the coin falls backwards.
