During a cliff diving competition, a diver begins a dive with his center of gravity 70ft above the water. The initial vertical velocity of his dive is 8ft per second.

a. Write and graph an equation that models the height [h] (in feet) of the diver's center of gravity as a function of time [t] (in seconds).

b. How long after the diver begins his dive does his center of gravity reach the water?
