The height, h (in feet), of a golfball is the function of the the time, t (in seconds), It has been in flight. A golfer strikes the ball with an initial upward velocity of 80 feet per second. The flight path of the ball is a parabola. The approixmate heigh of the ball above the ground is molded by : H(t)=-16t^2+80t

Q:Assume he ball lands in a location that is 7 feet higher in elevation than the point of initiation. Make a drawing showing the route of the ball. Determine the horizontal intercepts. What is he siginifcance of theses intercepts? Calculate the coordinates of the landing point.

Your looking to solve for t when 
h (t) = 7 for the landing point
