A person drops a coin. Describe the path of the coin as seen by the person if he is in (a) a car moving at constant velocity and (b) in a free falling elevator. (a) a car moving at constant velocity and (b) in a free falling elevator.
Ans : (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 w.r.t. the person. (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 w.r.t. the person.

a car moving at constant velocity and
Ans : 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.

#3-b
in a free falling elevator.
Ans : 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 w.r.t. the person.
