Asked by Nikki
A helicopter, starting from rest, accelerates straight up from the roof of a hospital. The lifting force does work in raising the helicopter. An 850-kg helicopter rises from rest to a speed of 6.9 m/s in a time of 3.8 s. During this time it climbs to a height of 9.4 m. What is the average power generated by the lifting force?
