Let the initial thrust be  F Newton.

Using Newton's second law of motion, we get 

                                       F\ -\ mg\ =\ ma

or                                                 F\ =\ ma\ +\ mg

                                                    F\ =\ m(a+g)\ N

Substituting values in this equation, we get :

                                          F\ =\ 20000(5+10)

or                                       F\ =\ 3\times 10^5\ N
