The function V= √1.223w expresses the landing speed, V (in feet per second), as a function of gross weight, w (in pounds), of an aircraft. Write an equation that expresses the gross weight of an aircraft as a function of its landing speed
an equation that expresses the gross weight of an aircraft as a function of its landing speed will be given as follows: V= √1.223w we make w the subject of the equation, we start by dividing both squaring both sides: V²=(√1.223w)² V²=1.223w next we divide both sides by 1.223 to get : V²/1.223=1.223w/1.223 w=V²/1.223 hence the answer will be w=V²/1.223
