Aeronautical mechanics question (1 Viewer)

[nthan]

Could anyone please help me out with a solution to this question(22) from the copeland book? I cannot seem to get the answer of 84.1kg...

A 650kg glider is descending at and angle of 15° at constant velocity. Determine the mass of the pilot if the glider has a lift to drag ratio of 5, and the drag force is 1900N.

Thanks
