The helicopter in the drawing is moving horizontally to the right at a constant velocity. The weight of the helicopter is W = 55600 N. The lift force generated by the rotating blade makes an angle of 21.0° with respect to the vertical.
(a) What is the magnitude of the lift force?
1 . N
(b) Determine the magnitude of the air resistance that opposes the motion.
2 . N
