Homework Help: Finding centripetal acceleration and velocity

  1. Sep 4, 2013 #1
    1. The problem statement, all variables and given/known data

    a) After take-off an airplane takes a U-turn tilting the plane 45 degrees to one side. The speed and height is constant. Find the centripetal acceleration.

    Mass: 79010 kg
    Engine Fmax: 2x 121.4 kN

    b) The U-turn took 47 seconds. What is the velocity in km/h of the airplane now?

    2. Relevant equations

    3. The attempt at a solution

    a) as = g*tan angle = 9.81 m/s * tan 45 = 9.81 m/s is the centripetal acceleration.

    b) I can't find any formulas on this... ?
