How far the aircraft slides before it comes to rest ?

  1. Mar 26, 2012 #1
    1. The problem statement, all variables and given/known data
    An aircraft has to make an emergancey landing on a runway
    without landing gear , if the aircraft lands at 40 m\s-1
    and μ is 0.5 ,
    How far the aircraft slides before it comes to rest ?



    2. Relevant equations
    X=2 μ g \ v2


    3. The attempt at a solution
    2 x 0.5 \ 20 = 2 m ?
    Using some website calculater result was : 1600 m
    I'm terribly lost
