2 At a football game, footballs are launched in a pre-game promotion. The balls are launched from a height of 1 m above the field. The vertical motion of a ball can be modelled by the relation h = −5t² + 30t + 1, where t is time in seconds, and h is the height in metres. If a fan stands at a height 26 m above the field, catches a ball when it is on the way down, how long was the ball in the air? (Hint: evaluate the zeros)
