Question

Please show me how to dothis. I will rate

A 25-ton (1 ton = 1000kg) airplane needs to land on a 120m-long airstrip at 250m/s speed. Most of the braking is provided by air dragof the plane’s wings. During the landing, how much averageforce does EACH wing need to endure? Please show me how to dothis. I will rate

Explanation / Answer

. 01.   1 metric ton = 1000kg 02.   d = d0 + v0*t +(1/2)*a*t2 03.   v = v0 + a*t . 04.   The solution to this problem requires yousolve two equations. 05.   d = 120 meters = 0.0 meters + (250m/s)*t + (1/2)*a*t2 06.   v = 0.0 = 250 m/s +a*t      ;   solve fora 07.   a = (-250m/s)/t      ;   substitutethis valve for a into '05' 08.   120 meters = (250 m/s)*t + (1/2)*[(-250m/s)/t]*t2 =125*t      solve for t 09.   t = (120 meters)/(125 m/s) = 0.960seconds   ;   use this value of t to solvefor a in '07' 10.   a = (-250 m/s)/(0.960 s) = -260.4167m/s2 11.   |Ftotal| = m*a =|(25)*(1000kg)*(-260.4167 m/s2)| = |-6510417.5Newtons| 12.   |Feach_wing| =(1/2)*(Ftotal) = |(1/2)*(-6510417.5 Newtons)| =3,255,208.75Newtons .
