The equation \( f(8) = 0 \) indicates that after 8 seconds from the launch, the rocket reaches a height of 0 feet. This means that at 8 seconds, the rocket has either landed back on the ground or reached the same height as the ground level, which typically indicates that it has completed its ascent and descent or is at the launch height again. In the context of the rocket's flight, this could signal the end of its flight or that it has touched down.

Mr. Kramer's physics class went to the football field to launch a rocket into the air. The rocket's height in feet, f(x), depends on the number of seconds, x, that have elapsed since launch.
What does f(8)=0 tell you?
