An airport has runways only 132 m long. A small plane must reach a ground speed of 40 m/s before it can become airborne.
What average acceleration must the plane’s engines provide if it is to take off safely from its airport?
Answer in units of m/s2

Vf^2 = Vo^2 + 2ad,
a = (Vf^2 - Vo^2) / 2d,
a = ((40)^2 - 0) / 264 = 6.1m/s^2.
