A person leaning off a cliff 230 meters above the ground shoots an object into the air with an initial vertical velocity of 30 meters per second. The equation h = -10t2 + 30t + 230 gives the height, h, of the object when it is in the air for t seconds. After how many seconds is the object at a height of 50 meters above the ground?
