Answer:
W = 27468000 [N] or 27.47 [kN]
Step-by-step explanation:
The weight of a body is defined as the product of mass by gravitational acceleration.

where:
W = weight of the rocket with fuel [kg]
m = mass = 2800000 [kg]
g = gravity acceleration = 9.81 [m/s²]
Now we can solve:
![W = 2800000*9.81\\W = 27468000 [N]](https://img.qammunity.org/2021/formulas/physics/college/wl0gzqkqbhwp1w24cjymif0chzoibl8np4.png)
