A helicopter, starting from rest, accelerates straight up from the roof of a hospital. The lifting force does work in raising the helicopter. An 760-kg helicopter rises from rest to a speed of 9.0 m/s in a time of 3.5 s. During this time it climbs to a height of 9.7 m. What is the average power generated by the lifting force?
