A rocket is launched following the path h = 64(3x + 1)2 ,where x is the horizontal distance and h is the vertical distance (height) the rocket has traveled from the launch pad. The vertical speed of the rocket is clocked at 12 mi/sec at a height of 1 mile. Simultaneously, it is noted that the vessel had drifted 5 miles from being directly above the launch pad. Find the horizontal speed of the rocket.
