A pair of equal gravitational forces ... one in each direction ...
exists between every speck of mass in the universe and every
other speck of mass.
Answer
given,
Pressure on the top wing = 265 m/s
speed of underneath wings = 234 m/s
mass of the airplane = 7.2 × 10³ kg
density of air = 1.29 kg/m³
using Bernoulli's equation




Applying newtons second law
2 Δ P x A - mg = 0


A = 3.53 m²
The kinetic energy is

and the height of the building doesn't matter at all.
