Web13 dec. 2009 · It depends on how far they've been falling and how they started falling. A bullet shot out of a gun aimed straight downward will travel faster than a ball dropped from the same height. And the speed will not remain constant.

Web5 apr. 2014 · Since drag is proportional to the square of the velocity, if you do this perfectly you would "only" experience 86g, Here switching perfectly means switching from a position with 50m/s terminal velocity to a position of 150m/s in the instance you hit the water. – Taemyr Jun 11, 2015 at 8:21
WebSo, yes, the object does start slower and will eventually reach speeds faster than 9.8 m/s, but that is velocity and not acceleration. The acceleration remains constant, and is reflecting the increasing velocity of the object as it continues to fall. The object won't stop accelerating until it hits the ground.
