Show me the steps to solve $3$ Engine$-$Out Effects

We will idealize the Boeing $757-300$ as depicted below to determine the effective yaw acceleration caused by losing thrust in one engine instantaneously. The entire aircraft has a mass of $116,500kg$ :

the wings $($including fuel but not engines$)$ have mass of $32,500kg$ each, which we will treat as being evenly distributed along the red dashed line through the wings

the fuselage and passengers$/$cargo have mass of $40,000kg,$ which we will treat as being evenly distributed along the $50$ m red dashed line along the fuselage length

we will count the tail separately as a point mass of $3,500kg,$ shown as the red dot at the rear of the plane $(50$ m from the nose$)$

each engine $\frac{?}{?}$ nacelle has mass of $4,000kg,$ which we also will treat as a point mass

The $757-300$ can use either Rolls$-$Royce RB$211$or Pratt & Whitney PW$2000$ turbofan engines, each of which produces approximately $190,000$ N of thrust. $($Note correction to $190,000$ N$,$ not $190,000$ kN$!)$

Assuming a flight condition using full engine thrust, determine the instantaneous yaw acceleration $($e$.$g$.,$ in $ra\frac{d}{s^2})$ if one engine is lost, i$.$e$.,$ it instantaneously drops to $0$ N of thrust.
