A ball is thrown vertically up from the ground. If the positive direction is upward, then h = -16t² + 48t feet gives the height of the ball after t seconds. An observer is 20 feet from the point where the ball was thrown. Find the rate at which the distance between the ball and the observer changing after 2 seconds.
