Given the equation:
[tex]h=-16t^2+48t[/tex]
Where (h) represents the height of the rocket, and (t) is the time
We will find when the rocket will be at the ground level
The ground will be at the ground level when (h=0), which means the x-intercepts of the given graph
As shown: the graph has two points of x-intercepts
The points are (0, 0) and (3, 0)
So, the answer will be:
The rocket is at ground level at ( 0 ) seconds and ( 3 ) seconds.
