The 190-kg lunar lander is descending onto the moon's surface with a velocity of 6.0 m/s when its retro-engine is fired. If the engine produces a thrust T for 3.8 s which varies with the time as shown and then cuts off, calculate the velocity of the lander when t- 4.7s assuming that it has not yet landed. Gravitational acceleration at the moon's surface is 1.62 m/s. The velocity is positive if moving downward, negative if up. 6.0 m/s TN 756 1.9 3.8 Answe: v m/s
