# A ball is dropped from the top of a tall building. At the same instant, a second ball is thrown upward from the ground level. When the two balls pass one another, one on the way up, the other on the way down, compare the magnitudes of their acceleration:

A ball is dropped from the top of a tall building. At the same instant, a second ball is thrown upward from the ground level. When the two balls pass one another, one on the way up, the other on the way down, compare the magnitudes of their acceleration:

- **A.** The acceleration of the dropped ball is greater.
- **B.** The acceleration of the ball thrown upward is greater.
- **C.** The acceleration of both balls is the same.
- **D.** The acceleration changes during the motion, so you cannot predict the exact value when the two balls pass each other.
- **E.** The accelerations are in opposite directions.
