The displacement of the plane during acceleration is 93.8 meters. The equation relating displacement, acceleration, and velocity is: Vf^2 = Vi^2 +2*a*d, where Vf is final velocity, Vi is initial velocity, a is acceleration, and d is displacement. Plugging the given values into this equation: 40^2 = (10)^2 + 2*8*d => 1600 = 100+16d => solve for d: d = (1600-100)/16 = 93.8 meters.
