If a stone is tossed from the top of a 190 meter building, the height of the stone as a function of time is given by h(t) = 9.8t2 – 10t + 190, 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 your answer.

Best ResponseYou've already chosen the best response.09.8t^2  10t + 190 = 190 t(9.8t10) = 0 t=10/9.8 Thus it will fall after 10/9.8 secs
