Question
A stone is released from an elevator going up with an acceleration a. The acceleration of the stone after the release is:
- a upward.
- (g - a) upward.
- (g - a) downward.
- g downward.
✓
Answer
- g downward
Gravity is the only force acting on the stone when it is released. And, we know that gravity is always in the downward direction.
