Suppose a person standing atop a building 398 feet tall throws a ball upward. If the person releases the ball 4 feet about the top of the building, the ball's height h in feet, after t seconds is given by the equation h = -16++ 48t + 402. After how many seconds will the ball be 338 feet from the ground?​
