n A person flips a coin into the air and it landson the ground a few feet away. (a) If the person were to performan identical coin flip on an elevator rising with constant speed,would the coin’s time of flight be greater than, less than, or equalto its time of flight when the person was at rest? (b) Choose thebest explanation from among the following:I. The floor of the elevator is moving upward, and hence itcatches up with the coin in mid flight.II. The coin has the same upward speed as the elevator when itis tossed, and the elevator’s speed doesn’t change during thecoin’s flight.III. The coin starts off with a greater upward speed because of theelevator, and hence it reaches a greater height.
