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.)
