The maximum height of the rocket is 43.89 feet

<h3>How to write the function</h3>

The general function is given as:

h(t) = -16t^2 + vt + h

The initial velocity is

v = 53

So, we have:

h(t) = -16t^2 + 53t + h

The initial height is

h = 0

So, we have:

h(t) = -16t^2 + 53t

Hence, the function of the height is h(t) = -16t^2 + 53t

<h3>The maximum height of the rocket</h3>

In (a), we have:

h(t) = -16t^2 + 53t

Differentiate the function

h'(t) = -32t + 53

Set to 0

-32t + 53 = 0

This gives

-32t = -53

Divide by -32

t = 1.65625

Substitute t = 1.65625 in h(t) = -16t^2 + 53t

h(1.65625) = -16 * 1.65625^2 + 53 * 1.65625

Evaluate

h(1.65625) = 43.890625

Approximate

h(1.65625) = 43.89

Hence, the maximum height of the rocket is 43.89 feet

<h3>Time to hit the ground</h3>

In (a), we have

h(t) = -16t^2 + 53t

Set to 0

-16t^2 + 53t = 0

Divide through by -t

16t - 53 = 0

Add 53 to both sides

16t = 53

Divide by 16

t = 3.3125

Hence, the time to hit the ground is 3.3125 seconds

<h3>The graph of the function h(t)</h3>

See attachment for the graph of the function h(t)
