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, where t is in seconds, and height is in meters.After how many seconds will the stone hit the ground? round to the nearest hundredth's place, include units in the answer.

The ground would be a height of zero. So set your equation equal to zero and solve.

0=-9.8t^2-10t+330
