A helicopter, starting at rest, accelerates straight upfrom the roof of a hospital. The lifting forces does work inraising the helicopter. An 810-kg helicopter rises from rest to aspeed of 7.0 m/s in a time of 3.5s. During this time it climbs to aheight of 8.2m. What is the average power generated by the lifting force?
