hi, Can somebody please help me solve this through completing the square? 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. a) Describe the path of the ball. b) After how many seconds does the ball reach the ground? c) 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 5 m in height?
