A rocket is launched straight up from the ground with an initial velocity of 224 feet per second.
a) At what time does the rocket reach its maximum height?
b)Find the maximum height of the rocket
==========================
That's not a rocket.
You ever seen a rocket launched? They have thrust engines, and the max height of some are out around Pluto and beyond.
That's a projectile.
----------------
Usually when the height is feet, the equation is h(t) = -16t^2 + 224t
----
h(t) = -16t^2 + 224t
The max ht is the vertex of the parabola, at t = -b/2a
