Homework Statement
An airplane of mass 25,000 kg (approximately the size of a Boeing 737) is coming in for a landing at a speed of 72 m/s. Calculate the normal force on the landing gear when the airplane lands. Hint: You will use 0.92 m as the compression (vertical displacement) of the landing gear shock absorbers when the plane contacts the ground and 5° as the angle that the landing velocity makes with the horizontal.
Homework Equations
The Attempt at a Solution
plane N 9.8*25000=245000N
a=vf^2-vi^2/2*-.92=36.31m/s
Fn=245000=25000*36.31=664750N*******
dy=-.92
viy=-6.27
vfy=0
a=36.39
Not sure what I am doing wrong
