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 9.0 m/s in a time of 4.5 s. During this time it climbs to a height of 8.4 m. What is the average power generated by the lifting force?
A helicopter, starting from rest, accelerates straight up from the roof of a hospital. The lifting force does work in raising the helicopter. An 820-kg helicopter rises from rest to a speed of 8.5 m/s in a time of 5.0 s. During this time it climbs to a height of 9.8 m. What is the average power generated by the lifting force?

A helicopter, starting from rest, accelerates straight up from the roof of a hospital. The lifting force does work in raising the helicopter. An 880-kg helicopter rises from rest to a speed of 10.0 m/s in a time of 5.0 s. During this time it climbs to a height of 7.6 m. What is the average power generated by the lifting force?
A helicopter accelerates upward, away from the surface of the earth, at 0.6 m/s2 while lifting a 1375.0 kg car. What is the tension in the cable (ignore the cable's mass), in N, that connects the car to the helicopter?
