W = ∫ (x from 0.1 to +oo) F dx 
= ∫ (x from 0.1 to +oo) A e^(-kx) dx 
= A/k x [ - e^(-kx) ](between 0.1 and +oo) 
= A/k x [ 0 + e^(-k * 0.1) ]

= A/k x e^(-k/10) </span>

Explanation:
There are three basic forces in aerodynamics: acceleration, which moves an airplane forward; drag, which holds it back; and height, which keeps it airborne. Lift is generally explained by three theories: Bernoulli's principle, the Coanda effect, and Newton's third law of motion.
