Physics Homework: What is the magnitude of the lift force?

The helicopter in the drawing is moving horizontally to the right at a constant velocity. The weight of the helicopter is W = 59500 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?


(b) Determine the magnitude of the air resistance that opposes the motion.
