Question
The five engines of the first stage of a launch vehicle provide a total thrust of
31.5 x 106
newtons to the space vehicle (launch vehicle and spacecraft). Assuming the acceleration is
uniform, calculate the acceleration of the 2.764 x 106 kg space vehicle after lift-off. The average air
resistance is 180 kN.

Answers
a = (Fe-Fa)/M =
(31.5*10^6-0.18*10^6)/2.764*10^6 =
31.32*10^6/2.764*10^6 = 11.33 m/s^2
(31.5*10^6-0.18*10^6)/2.764*10^6 =
31.32*10^6/2.764*10^6 = 11.33 m/s^2
