A helicopter, starting from rest, accelerates straight up from the roof of a hospital. The lifting force does work in raising the helicopter. An 890-kg helicopter rises from rest to a speed of 7.6 m/s in a time of 2.9 s. During this time it climbs to a height of 8.7 m. What is the average power generated by the lifting force?
