The helicopter is moving horizontally to the right at a constant velocity. The weight of the helicopter is W=56500N. The lift force L generated by the rotating blade makes an angle of 21.0 degrees with respect to the vertical. What is the magnitude of the lift force? Determine the magnitude of the air resistance R that opposes the motion.
