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) = -9.8t2 – 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 your answer.
0 = -9.8t2 - 10t + 330
The formula is wrong.
That should be -4.9 t^2 as the first term, not -9.8 t2. They should be using g/2, not g, as the coefficient.
If the formula were correct, you would set h(t) = 0 and solve for t.
Alwas use a ^ in front of an exponent when typing questions.
