A certain crane can provide a maximum lifting force of 25 000 N.  It hoists a 2000-kg load starting at ground level by applying the maximum force for a 2-second interval; then, it applies just sufficient force to keep the load moving upward at constant speed.  Approximately how long does it take to raise the load from ground level to a height of 30 m?
