A small model rocket is launched straight up into the air. After rising to its highest point, its parachute fails to open and the rocket falls straight back to the ground. Let h(t)=-4.9t2+30t represent the height of the rocket in meters, dependent on the time, t, in seconds. The function is only valid for times t such that t is greater or equal to the start time and less than or equal to when it hits the ground.
