GP Motion Force

A passenger in a moving train tosses a coin upward which falls behind him. It implies that the motion of the train is

  1. uniform
  2. retarded
  3. accelerated
  4. along the circular tracks

Answer

If the speed of the train is constant, the coin will fall as if the train was stationary. If the train was slowing down (retarded), the coin would be moving faster than the train, coin would fell ahead of the passenger.
