The rocket shown in the figure below is about to be launched. The total mass of the rocket and its full load of fuel is 2.8 × 10^6 kg

Question

The constant force provided by the rocket’s motors is 3.2 × 10^7 N.

(a) Calculate (i) the total weight of the rocket and the fuel,

Answer 1

The total weight of the rocket and the fuel would simply be:

F_g = m_Total g = (m_rocket + m_fuel) g = (2.8X10⁶ kg) (9.8 m/s²) = 2.744X10⁷ N
