#### Solution

When the person drops the coin, the path of coin as seen by the person if:

a) In the car, the path of the coin will be vertically downward because the only force acting on the coin is gravity in the downward direction.

(b) In a free falling elevator, the coin as well as the person will be in a condition of weightlessness. So, the coin will remain stationary with respect to the person.

Because all fee falls objects weightlessness.
