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.


W = m*g

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]
