Given:

m=52000000kgm=52\:000\:000\:\rm kg

Fthrust=25800000NF_{\rm thrust}=25\:800\:000\:\rm N

Fresistive=5000000NF_{\rm resistive}=5\:000\:000\:\rm N


The Newton's second law says

a=Fnetm=FthrustFresistivema=\frac{F_{\rm net}}{m}=\frac{F_{\rm thrust}-F_{\rm resistive}}{m}

a=25800000500000052000000=0.4m/s2a=\frac{25800000-5000000}{52000000}=0.4\:\rm m/s^2
