According to the National Association of Rocketry, the current model rocket altitude record in the "F Altitude" event for Ages 14-18 division is 1430 meters. From this record-setting altitude, the rocket is motionless as it begins its free-fall descent back to the ground. Using the equation,

h() = 4.92 + 0 + h0, find how long it will take for the rocket to hit the ground after reaching its high point.

(Hint: motionless implies 0 = 0 and hitting the ground implies h() = 0. )
