Chapter D3, Problem D3/149 The 174-kg lunar lander is descending onto the moon's surface with a velocity of 5.0 m/s when its retro-engine is fired. If the engine produces a thrust T for 3.2 s which varies with the time as shown and then cuts off, calculate the velocity of the lander when t = 3.9 s assuming that it has not yet landed. Gravitational acceleration at the moon's surface is 1.62 m/s2. The velocity is positive if moving downward,...

Chapter D3, Problem 03/149 The 222-kg lunar lander is descending onto the moon's surface with a velocity of 4.3 m/s when its retro-engine is fired. If the engine produces a thrust T for 5.8 s which varies with the time as shown and then cuts off, calculate the velocity of the lander when t - 6.7 s 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,...
