1-The A-4D Skyhawk has the following properties: S=28m^2,b=9m and bar (c)=3.54m . If the aircraft is flying at M=0.4 at sea level (a=340m/s,rho =1.225kg/m^3) , and C_(m_(q))=-3.6 determine the pitching moment change resulting from a change in pitch rate of +10deg/s

To determine the pitching moment change resulting from a change in pitch rate, we can use the following formula: Where:- is the change in pitching moment- is the wing area- is the mean chord length- is the mean aerodynamic chord- is the angle of attack- is the rate of change of angle of attackGiven:- - - - - - - - First, we need to calculate the angle of attack ( ) using the Mach number ( ) and the speed of sound ( ): Substituting the given values: Next, we can calculate the pitching moment coefficient ( ) using the given value: Now, we can calculate the pitching moment change ( ): Substituting the given values: $\
