20070313 

From san: A football player attempts a field goal by kicking the football. The ball follows
the path modelled by the equation h= 4.9^2+10t+3, where h is the height of the
ball above the ground in metres, and t is the time since the ball was kicked
in seconds.
*the ball must clear the uprights for the field goal to count. The uprights are approximately
5 m high. How long does the ball stay above 5 m in height? Answered by Penny Nom.
