Jack is standing on the roof of his house and kicked a rubber ball in the air for it to land on the ground for his dog Henry to fetch. The ball is launched into the air from the height of 12 feet at a time t=0. The function that models this situation is h(t)=-2t^2+10t+12, where t is measured seconds and h is the height in feet.

When will the ball ht the ground?
