If a toy rocket launched vertically upward from the ground level, where h is the height and t is the seconds, given the equation h (t)=-16t^2 +128t
A. How long will it take for the rocket to return to the ground?
The height is h(t)=-16t^2 +128t
Solve for t then h(t) = 0
======================
B. How long will it take the rocket to hit it's [sic] maximum height?
Max of h(t) is the vertex of the parabola, at t = -b/2a
---------------
C. What is the maximum height?
Max ht if f(t of max ht)
