We have
Va(airplane)=150 East
Vw(wind)=7.1 South East
resulting vector R
airplane
Vax=150 Vay=0 it only has component x
Wind
Vwx=7.1*cos45=5.02
Vwy=7.1*sin45=-5.02 is negative because is South direction
|R|=(Rx^2+Ry^2) ^0.5
Rx=150+5.02=155.02
Ry=0-5.02=-5.02
|R|=155.10 miles/hour South EastDetermine angle θ
Rx=R*cos(θ)
Cos(θ)=Rx/R Cos(θ)=155.02/155.10=0.9995θ =arc cos Rx/R θ =1.8119 º
Rx represents the component in the East direction of the resultant force. Your contribution is given by both, the force of the plane and the wind. The contribution of the wind makes the airplane's speed greater
Ry represents the component in the South direction of the resulting force Its contribution is exclusive of the wind since the airplane has no component in this direction
|R| the force resulting from the combined action of the force of the plane and the force of the wind
θ represents the angle that forms the resultant force with respect to the x axis or east direction
