Best Answer

The thrown ball will (usually) have the highest velocity as the acceleration (resultant of force) used to throw it exceeds that of the other two balls. The ball thrown upward will have a higher downward velocity than the dropped ball even though their accelerations (due to gravity) are the same, as it has more time to travel downward.

Although, If the ball thrown upward is thrown high enough, it may even travel faster than the ball thrown downward if the downward throw's force is not enough to beat the ball's terminal velocity (quite a bit of height would be required though).

### The downward force of gravity and the upward force of air resistance on a ball?

0 meters per second squared As stated above, the ball will have zero acceleration due to the equal upward and downward forces, presuming the ball is moving or attempting to move in an upward or downward direction. The ball, in fact, will not be moving at all in this situation, but will be suspended in its position. If you are referring to an acceleration or motion in a direction that is not vertical, you will need to provide other information in order to get an answer.
