Velocity -- plane takeoff speed and distance

  1. Aug 21, 2014 #1
    1. The problem statement, all variables and given/known data
    A light plane must reach a speed of 33m/s for takeoff. How long a runway is needed if the (constant) acceleration is 3.0m/s^2.


    2. Relevant equations

    v^2=2*a*d

    3. The attempt at a solution
    v^2/(2*a)=d
