We just consider the moves of the jumbo jet, not it's causes (we solve it kinematically)
It has a constant acceleration, so then we may use this equation to solve our problem: a = Vf^2 - Vo^2 / 2∆x
Vf (The max velocity that allowed) = 360 Km/h
Vo = 0 (At rest)
∆x = 1.5 Km
then..
a = (360)^2 / (2)(1.5) = 43200 Km/h^2
Convert those numbers to m/sec^2 you will surprised by the results=))
