I've been trying out this problem for hours and can't figure it out.
A helicopter is moving horizontally to the right at a constant velocity. The weight of the helicopter is W = 52100 N. The lift force vector L generated by the rotating blade makes an angle of 21.0° with respect to the vertical.
Find the magnitude of the Lift force. And find the resultant vector R.

At first i tried doing 52100sin69 for the lift..but that is not the correct answer...STUCK!
