# Aeroplane Dynamics for Maximum Take-Off

The maximum take-off mass of an Airbus A380 passenger jet is about 600 000 kg. The lift is provided by the wings, which have a total area of 845 m2.

Calculate the following:

A) The approximate take-off velocity of the jet when the lift coefficient of its wings reaches 2.1, stating any assumptions you make in your calculation (you should take the air density to be 1.225 kg mâ?'3 and the acceleration due to gravity to be 9.81 m sâ?'2)

B) The minimum thrust required from its engines to accelerate the jet to the take-off velocity calculated in part (i), if the runway length is 2.9 km
