$2.777\ m/s^2$

Explanation:

The least acceleration $a$ of jumbo jet starting from rest $u=0$ to reach a velocity of $v=360\ \text{km/hr}=100\ m/s$ running on runway of $s=1.8\ km=1800\ m$ to take off is given by third equation of motion

$v^2=u^2+2as$

$100^2=0^2+2a(1800)$

$a=\frac{10000}{3600}$

$a=2.7777\ m/s^2$
