When Cam Newton throws the football, the path of the football can be modeled using the formula, h(t) =
4.9t^2 +6t+ 8 where h(t) represents the height of the football from the
ground in meters and t represents the time the football is in the air in seconds. Approximately
how long will it take the football to hit the ground?
