Problem 21.1
Above the earth's atmosphere at an altitude of 400 km where the acceleration due to
gravity is 8.69 m/s², a certain rocket has a total remaining mass of 300 kg and is directed 30°
from the vertical. If the thrust 7 from the rocket motor is 4kN and if the rocket nozzle is
tilted through an angle of 1° as shown, calculate the angular acceleration a of the rocket
and the x and y components of the acceleration of its mass centre G. The rocket has a
centroidal radius of gyration of 1.5m.
