9. A lunar lander with a mass of 15,000 kg is descending onto the moon's surface with a velocity of 2 m/s when it fires its retro-engine to produce a time-dependent thrusting force of T = (14t) kN where t is in seconds over a time of 4 seconds. Determine the velocity of the lander after the 4- second thrusting event has completed. The gravitational acceleration of the moon is 1.62 m/s' at the moon's surface.
