an elevator is descending at a constant speed.a passenger drops a coin to the floor.what accleration would (1)the passenger and(2)a person at rest with respect to the elevator shaft observe for the falling coin?

Both would see the same acceleration, so they would both travel 10 metres per second faster each second. So, after 5 seconds the coin would be travelling at 50m/s (if there wasn't a floor). The only difference between the person at rest and the passenger is that the person at rest would see the coin's speed plus the elevator's speed (initial velocity) - it would look normal to both the observer and the passenger.

Both would observe the coins rate of descent at the same acceleration of 32feet / sec per sec.Everything within the elevator is travelling at the same speed, therefore the coin,s acceleration would appear normal to the occupant of that elevator as it would to the outside observer.

Both would observe the same acceleration.
The observer at rest would only note a
difference in the initial velocity.
