A person standing on the floor of an elevator drops a coin. The coin reaches the floor of the elevator in a time
t1 if the elevator is stationary and in time t2 if it is moving uniformly. Then:
(a) t1 = t2 (b) t1 t2 or t1
I feel that the answer is d. When the coin is detached from hand of the person, it is on its own and accelerated downward. But at the same elevator is moving up which is now a separate system. So it seems that the coin will have to cover a smaller distance than in the case if the elevator was stationary since both are approaching each other. If I am in the elevator I would definitely see that the coin covers same distance and I would do with answer a. But if I am on ground, I would see the elevator and coin approaching towards each other. What is actually correct?
