You can put this solution on YOUR website!
The formula should be
d=4.9t%5E2%2BV%5B0%5D%2At where
V%5B0%5D= initial downwards velocity in meters per second %28m%2Fs%29 ,
t = time in seconds %28s%29 , and
d= distance fallen, in meters %28m%29.
Once you have the right formula, all you need to do is plug in your known values;
V%5B0%5D=10 and t=6

d=%284.9%296%5E2%2B10%2A6=4.9%2A36%2B60=176.4%2B60=highlight%28236.4%29

NOTES:
Maybe the formula you were given has a different symbol for the distance fallen, but it is not the number 5.
The 4.9 factor is a constant with units of m%2Fs%5E2 .
If you were in physics class you would know that 4.9m%2Fs%5E2 is half of the acceleration of gravity on (or near) the surface of planet Earth.
