Amodel rocket was launched from the top of a building. the rocket's approximate height can be modeled by the quadratic equation h = -4.9t2 + 53.9t + 127.4, where h is the rocket's height, in meters, after t seconds. when factored, this equation is h = -4.9(t - 13)(t + 2). what is a reasonable time for it to take the rocket to land on the ground?
