A spiral transition curve is used on railroads to connect a straight portion of the track with a curved portion. If the spiral is defined by the equation y = (10-6)x³, where x and y are in feet, determine the magnitude of the acceleration of a train engine moving with a constant speed of 40 ft/s when it is at the point where x = 600 ft. y (10)x = 40 ft/s
