Answer 1

Answer:

• h = -16t^2 +192t
• maximum

Step-by-step explanation:

In order to fill in the values in the given function, we need to assume an initial height for the firework. It is convenient to assume that height (h0) is zero. We are given that v0 = 192, so the model is ...

  h = -16t^2 +192t

___

Since the initial upward velocity is well below escape velocity, the firework will eventually fall back to Earth. The height function will have a maximum.

Answer 2

Answer:

$\displaystyle h(t) = -16t^2 + 192t; Maximum$

Step-by-step explanation:

Maximum Value → Parabola opens downward [−A]

Minimum Value → Parabola opens upward [A]
