The stall speed of the airplane under a load factor of 2.5 gs is 90 knots.
A stall speed is slowest speed a plane can fly to maintain level flight. Normally, when a plane slows down it makes less lift. If the plane tilts its wings up, also known as increasing its angle of attack, it can compensate for any lift lost.
From the chart or graph of load factor vs unaccelerated stall speed, the stall speed of the airplane is determined as follows;
stall speed = 90 knots
Thus, the stall speed of the airplane under a load factor of 2.5 gs is 90 knots.
