"A model rocket is projected straight upward from the ground level according to the height equation, h = -4.9t² + 81.8t, where h is the height in feet and t is the time in seconds."
"For what length of time was the rocket above 200 feet?"
"If the rocket was launched from a 5 ft high launch pad instead of the ground, the equation would become h = -4.9t² + 81.8t + 5. Using the discriminant, determine if the rocket would ever reach a height of 400 ft."
Can't be that hard.
