When airplanes land or take off, they always travel along a runwayin the direction that is "into" the wind. This is because the "liftforce" on an airplane wing depends on the speed of the airplanerelative to the air (vrel mi/h). The lift force is proportional tov2rel. Consider a case in which a runway is parallel to the x axis,and the wind velocity is vwind = +18 mi/h (directed along+x).
(a) In what direction should the plane travel to takeoff (along +xor -x)?
i got -x
but i cant find part b) which is ....(b) Estimate the speed of atypical airplane (e.g. a Boeing 737) relative to the runway as ittakes off to be about 142 mph. Find the ratio of the lift force foran airplane that travels into the wind, to the lift force when ittravels in the opposite direction.
