A football player attempts a field goal by kicking the football. The ball follows the path modelled by the equation h=-4.9t2(means t squared)+10t+3, where h is the height of the ball above the ground in metres, and t is the time sincethe ball was kicked in seconds.
1. Describe the path of the ball.
2. After how many seconds does the ball reach the ground?
3. The ball must clear the uprights for the field goal to count. The uprights are approximately 5m high. How long does the ball stay above 5m in height?
This solution is comprised of a detailed explanation to describe the path of the ball and after how many seconds does the ball reach the ground.
