A jumbo jet must reach a speed of 360 km/h ( = 225 mi/h) on the runway for takeoff. assuming a constant acceleration and a runway 1.50 km long, what minimum acceleration from rest is required?

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=))
