2. You are simulating a lunar lander with 600-kg mass is descending onto the moon's surface with a velocity of 3 m/s when its retro-engine is fired. If the engine produces a thrust T for 5 s which varies with the time as shown and then cuts off, calculate the velocity of the lander when t=6 s, assuming that it has not yet landed. Use g = 1.60 m/s as the gravitational acceleration at the moon's surface. 의 TN) 600 kg 1800 T 5 1 (Hint) You need to include impulses due to its self-weigh (for 6 s), and the thrust (for 3 s + 2 s)
