<PRE><B>Question 366047</B>
It hits the ground when h(t) = 0.
Solve the equation for t.
----------------
h(t) = -9.8t2 – 10t + 230 = 0
------------------
If this happens on Earth, it should be h(t) = -4.9t^2 – 10t + 230, not 9.8t^2
------------------
Using 9.8:
*[invoke solve_quadratic_equation -9.8,-10,230]
------------
Using 4.9:
*[invoke solve_quadratic_equation -4.9,-10,230]
--------------
Ignore the negative values.
t = x in seconds
