A ball was kicked into the air from a balcony 20 feet above the ground, and the ball's height above the ground, in feet, t seconds after the ball was kicked was h(t) = 20 - 16t2 + 32t. ... Therefore, the maximum height, in feet, of the ball above theground after it was kicked was h(1) = 20 - 16(1)2 + 32(1) = 36.
