The Millenium Falcon spaceship was flying above the surface of the planet Alderaan when it was travelling at a horizontal speed of 2040 m/s. To descend to the Alderaan's surface, the Millenium Falcon needed to reduce its speed using its rocket, as shown in FIGURE 7 Direction of Alderaan's surface 1 FIGURE 7 Direction of motion. Millenium Falcon FIGURE 8 a. The average thrust from the rocket was 30 kN, and the mass of the Millenium Falcon was 15100 kg. Calculate the horizontal deceleration of the Millenium Falcon. Direction of Alderaan's surface I ← b. The rocket was then used to control the velocity of descent so that the Millenium Falcondescended vertically with a constant velocity, as shown in FIGURE 8. Due to the use of fuel during the previous deceleration, the mass of the Millenium Falcon had fallen by 53%. (acceleration due to gravity near the Alderaan's surface = 1.61 ms-²) rocket ii. Calculate the thrust force needed to maintain a constant vertical downwards velocity. i. Draw force vectors on FIGURE 8 to show the forces acting on the Millenium Falconat this time. Label the vectors.
