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. It will accelarate at a rate of 32 ft/sec2 until it reaches a terminal velocity due to friction. In other words, it will get faster … Web31 mei 2024 · How do you calculate the speed of a rock falling? To find out something’s speed (or velocity) after a certain amount of time, you just multiply the acceleration of gravity by the amount of time since it was let go of. So you get: velocity = -9.81 m/s^2 * time, or V = gt. The negative sign just means that the object is moving downwards.
