Question
Find the force required to give a helicopter of mass 2000 kg an acceleration of 0.10g upward in Newtons.
Find the work done by this force to lift the helicopter 150 m into the air.
A helicopter's engine produces a maximum power of 100000 W. How many seconds would it take the helicopter to reach an altitude of 150m?

F = ma (include g)
work = force * distance
power = work/time
work = force * distance
power = work/time

A toy helicopter flies forward with a force of 15 N into an oncoming wind of 10 N. The force of gravity pulls the helicopter down with a force of 5 N, but the propeller is providing an upward force of 10 N.
