An airport has runways only 130 m long. A small plane must reach a ground speed of 41 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/s^2.

Distance = 130m

Velocity = 41m/s

Find the time it'll take for the aeroplane to be airborne.

from,

V = S/t

t = S/V

t = 130/41

t = 3.17s

then to find acceleration,

a = V/t

a = 41m/s/3.17s

a = 12.93 m/s²
