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... ?
