You can put this solution on YOUR website!
s+=+%28-1%2F2%29gt%5E2+%2B+vt+
This is a very general equation for an object travelling down towards the ground.
"S" is the distance the object travelled at any given time
"g" is gravity
"v" is velocity or speed
"t" is time.
For these type of problems the "g" is typically assumed to be g+=+9.8%28m%2Fs%5E2%29+
-------but if you must solve for "g" given the equation then rewrite.....
s+=+%28-1%2F2%29gt%5E2+%2B+vt+
becomes s-vt+=+%28-1%2F2%29gt%5E2+
becomes %28-2%29%28s-vt%29+=+gt%5E2+
becomes %28%28-2%29%28s-vt%29%29%2Ft%5E2+=+g+
