Question
A stone is released from an elevator going up with an acceleration a. The acceleration of the stone after the release is:
  1. a upward.
  2. (g - a) upward.
  3. (g - a) downward.
  4. g downward.

Answer

  1. g downward

Explanation:

Gravity is the only force acting on the stone when it is released. And, we know that gravity is always in the downward direction.
