Question 1089544
.
<pre>
Your basic function for the height above the ground as the function of time is 

          h(t) = {{{-16t^2 + 200t + 50}}}.


<U>MEMORIZE</U> :  a)  the number 16 is the half of the gravity acceleration  g = 32 ft/s^2;  the first term  -16t^2  goes with the sign "-" (minus).

            b)  the vertical velocity stands as the coefficient at t  (200)  (positive if the initial velocity is directed up);

            c)  the initial height stands as the constant term (50).
