The height of an object can be represented as a function of time.

It takes the rocket 25 seconds to hit the ground

The height function is given as:

\mathbf{h(t) = 400t - 16t^2}

When the rocket hits the ground, we have:

h(t) = 0

So, the height function becomes

\mathbf{ 400t - 16t^2 = 0}

Rewrite as:

\mathbf{ 16t^2 = 400t}

Divide both sides by 16t

\mathbf{ t = 25}

Hence, it takes the rocket 25 seconds to hit the ground
