Hola no se resolver el siguiente problema:
(For this question use annex 031-1580A)
A jet aeroplane, with the geometrical characteristics shown in the appendix, has a take-off weight (W) of 460 000 N and a centre of gravity (point G on annex) located at 15.40 m from the zero reference point.
At the last moment the station manager has 12 000 N of freight added in the forward compartment at 10 m from the zero reference point.
The final location of the centre of gravity, calculated in percentage of mean aerodynamic chord AB (from point A), is equal to:
