Jason jumped off a cliff into the ocean in Acapulco while vacationing with some friends. His height as a function of time could be modeled by the function h(t) = -16t2 + 16t + 480 , where t is seconds and h is the height in feet.
a. How long did it take for Jason to reach his maximum height?
1/2 a second
