Asked by Talbert
A model rocket is launched vertically upward so that its height (measured in feet) t sec after launch is given by the following.
h(t) = -16t2 + 272t + 8
(a) Find the times when the rocket is at a height of 488 ft.
t = sec (smaller value)
t = sec (larger value)
(b) How long is the rocket in flight? (Round your answer to the nearest whole number.)
