###### A helicopter, starting from rest, accelerates straight up from the roof of a hospital. The lifting force does work in raising the helicopter. An 856-kg helicopter rises from rest to a speed of 6.2 m/s in a time of 3.81 s. During this time it climbs to a height of 9.33 m. What is the average power generated by the lifting force? (g = 9.80 m/s2)

A helicopter, starting from rest, accelerates straight up from the roof of a hospital. The lifting force does work in raising the helicopter.
