A ball is kicked straight up front an initial height of 2,5 ft with an initial velocity of 45 ft per second. The equation y=-16x^2+45+2.5 models it’s path, where y is height(in ft) of the ball and x is the time (in seconds) after the ball is kicked. How long will it take for the ball to reach the ground?
