SOLUTION
The object would hit the ground at the root of the equation, that is where h = 0
So we have

Solving the quadratic equation, we have

So we ignore -1 as time cannot be negative.
Hence the object hit the ground in 3 seconds
The answer should be (x-4)^2+(y+2)^2=radical 26
<span>A = letter 1 in alphabet
E = letter 5 (fifth one along from start)
F = letter 6
H = letter 8
then go in reverse:
Z = letter 26
V = letter 22 (or 5th one along from end)
U = letter 21 (next one back)
S = letter 19 (skip one as there was between F and H but going backwards) </span>
