Homework Help: Given acceleration and velocity; find length

  1. Oct 7, 2011 #1
    1. The problem statement, all variables and given/known data
    An aircraft takes off at 213 km/h after accelerating from rest at 2.86 m/s2. What is the minimum runway length required?

    2. Relevant equations

    3. The attempt at a solution
    I know it's super simple, but I can't figure it out. I know I have to convert 213km/hr to m/s, but then what?

    List your kinematics equations. Which ones involve acceleration, distance, and velocity? Try to pick one that doesn't need time.
