The helicopter in the drawing is moving horizontally to the right at a constant velocity. The weight of the helicopter is W=41600 N. The lift force L 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 R that opposes the motion.

find
Lx = Lsin21
Ly = Lcos21
y direction,
Lcos21 - 55600 = 0
L =44559.63N
x direction
Lsin21 - Fair = 0
where F air= 15968.74N
