The helicopter in the drawing is moving horizontally to the right at a constant velocity. The weight of the helicopter is W = 53 800 N. The lift force `vec(L)` generated by the rotating blade makes an angle of `21.0^(@)` with respect to the vertical as shown in the following figure. What is the magnitude of the lift force ?

18 800 N

57 600 N

20 600 N

37 600 N
