A stone is released from an elevator travelling upward with an acceleration . Following its release, the acceleration of the stone is
Options
- A downward
- B upward
- C upward
- D downward
Correct answer
D. downward
Step-by-step solution
When the stone is released from the elevator, it loses contact with it and is in a state of free fall.
The only force acting on the stone is the gravitational force of the earth, which acts vertically downward.
Therefore, the acceleration of the stone is the acceleration due to gravity, downward.
The acceleration of the elevator only affects the initial velocity of the stone at the moment of release, not its acceleration after release.
