Step 1

1 of 3During free fall, the falling object **is purely accelerated by gravity**, ie. it accelerates at $\mathrm{g=9.81\ \frac{m}{s^2}}$. This is acceleration, what we need is speed.

To determine the speed, we will make use of the following kinematic equation:

$\mathrm{v_f=v_i+at}$

where:

- vf is the object's
**final speed**; - vi is the object's
**initial speed**; - a is the object's
**acceleration**; - t is the object's
**travel time**.
