Check the picture below.
so.. the maximum point is at
and it happened after
--------------------------------------------------------------------------
now, when the rocket reaches the ground, as you saw on the picture, y = 0, thus
"t" is an amount in seconds, for this specific phenomena, it cannot be negative, so -10 is not a feasible value.
