Brick A is dropped from the top of a building.Brick B is thrown straight down from the same building,and neither one experiences appreciable air resistance.Which statement about their accelerations is correct?
A)The acceleration of A is greater than the acceleration of B.
B)The acceleration of B is greater than the acceleration of A.
C)The two bricks have exactly the same acceleration.
D)Neither brick has any acceleration once it is released.

Quizplus · Accepted Answer

The acceleration of both the bricks will be equal because the acceleration due to gravity is the same for all objects, regardless of their mass or initial velocity. The acceleration due to gravity is approximately 9.8 m/s^2. Therefore, both the bricks will have an acceleration of 9.8 m/s^2 towards the ground.
