Question 593595
If a stone is tossed from the top of a 230 meter building, the height of the stone as a function of time is given by h(t) = -9.8t^2 – 10t + 230, 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.
--------------
The other tutor got the right answer, ~ 4.36 seconds, but
if you're on Earth, the equation is
h(t) = -4.9t^2 – 10t + 230
