Question 1184741
.
<pre>

The general formula is


    h = {{{(gt^2)/2}}},


where h is the height of the free fall in meters, t is the time in seconds, g is the gravity acceleration g = 9.81 m/s^2.


For example, for t = 2 seconds (one of the examples from list)


    h = {{{(9.81*2^2)/2}}} = 19.62 m.


For other cases, use the formula and make calculations  ON  YOUR  OWN  by the same way,  as instructed.
