4 A passing submarine makes contact with the chain that attaches a buoy to the ocean floor. The buoy becomes submerged under the water upon the submarine's initial contact with the chain and does not resurface for 6 seconds. If the buoy's vertical height with respect to the ocean's surface follows a parabolic model over time, which of the following equations could give H, the buoy's vertical height x seconds after the submarine struck the chain? A) H =(x-6) -10 B) H=-1(x-6)- -12 O H =x -6x D) H=-x- +36
