the height of a small rock falling from the top of a 124 - ft - tall building with an initial downward velocity of - 30 ft/sec is modeled by the equation h(t)=-16t^{2}-30t + 124, where t is the time in seconds. for which interval of time does the rock remain in the air?\no t = 2\no - 2 < t < 0\no 0 < t < 2\no t > 2
