Finding centripetal acceleration and velocity

[FreshyT]

Homework Statement

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?

Homework Equations

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... ?
