the lifting force, f, exerted on an airplane wing varies jointly as the area, a, of the wing's surface and the square of the plane's velocity, v. the lift of a wing with an area of 290 square feet is 25,100 pounds when the plane is going 80 miles per hour. find the lifting force on the wing if the plane speeds up to 130 miles per hour.

Aristotle famously defined a force as something that causes an object to move in a "unnatural manner." Sir Isaac Newton was among the first scientists to investigate gravity and force. Any kind of force is simply a push or a pull. It can be characterized as a push or pull on an object.

Force is an external element that may change the condition of rest or motion of a body. It has a magnitude as well as a direction. The direction of the force is the place where force is applied, and the application of force is the location where force is applied.

A spring balance may be used to calculate force. Newton is the SI unit of force (N).

f=k x a x v^2

f=25,100

v=80

a=290

25100=kx290x(80)^2

k=25100/290x6400

=25100/1856000

=0.013523

therefore k= 0.013523

and so f=kxaxv^2

f=0.013523x290x(130)^2

=0.013523x4901000

f = 66276.223
