A football player kicks a football into the air. The football's height, h, in meters, with respect to the amount of time, t, in seconds, since it was kicked can be modeled by the quadratic function h= - 4.92 + 19.6.
Enter the number of seconds, t, it takes for the football to reach its maximum height.
