The ground is height = 0, so set the function equal to zero and solve the resulting quadratic equation for 
. Discard the negative root since you don't care what happened before you threw the stone (do you?).

Which way was the stone thrown; up or down? Hint: look at the coefficient on the first degree term. Up is +, Down is -.

If a stone is tossed from the top of a 330 meter building the height of the stone as a function of time is given by h(t)=-9.8t^2-10t+330
---------------
That might be true somewhere, but on Earth, it's
h(t)=-4.9t^2-10t+330
------------
-4.9 m/sec/sec, negative falling, approximate value.
