## 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 im doing wrong
