Data from in Example 9
Transcribed Image Text:
EXAMPLE 9 Using a Quadratic Function in an Application If a small rocket is launched vertically upward from ground level with an initial velocity of 128 ft per sec, then its height in feet after t seconds (if air resistance is neglected) can be modeled by the function h(t) = 16t² + 128t. After how many seconds will the rocket be 220 ft above the ground?
