A diver jumps from a dividing board 60 feet above the water with an initial
velocity of 12 feet per second. The height h, in feet, of a the diver t seconds
after he jumped can modeled by the function h(t) = -1612 + 121 + 60. how many seconds does it take the driver to reach its maximum height?
b) what is the drivers maximum height?
and c) how many seconds will it take to reach the surface of water
