Given that

Mass of the rocket m = 20000 kg

Initial acceleration a = 5.0 m/s^2   

Acceleration due to gravity g = 9.8. m/s^2

Step 1:  Set up an equation for the net force acting on the rocket  

The rocket must move upwards against gravitational force, and the blast's total initial thrust(force)

Net force F_{net} = F_g + F_b

F_{net} = mg + ma

F_{net} = m (g + a)

Step 2:  Determine the total force required to lift the rocket.

F_{net} = 20000 kg (9.8 m/s^2 + 5 m/s^2)

F_{net} = 20*10^3(14.8)

F_{net} = 296 *10^3 N

Hence, the total force(thrust) required to launch the rocket into the air., F_{net} = 296 *10^3 N
