The 15 200-kg lunar lander is descending onto the moons surface with a velocity of 2 m/s
Question:
The 15 200-kg lunar lander is descending onto the moon’s surface with a velocity of 2 m/s when its retro-engine is fired. If the engine produces a thrust T for 4 s which varies with time as shown and then cuts off, calculate the velocity of the lander when t = 5 s, assuming that it has not yet landed. Gravitational acceleration at the moon’s surface is 1.62 m/s2.

For the last three years, I've been employed by a construction business that specializes in the building of bridges, skyways, and power plants. My primary responsibility is to calculate the quantities of various supplies and equipment that will be required on the job site. In addition, we carry out feasibility assessments, material testing, and structural strengthening for projects of varying sizes and complexity.
When I have free time, I also teach students online. My goal is to assist them better grasp their studies and to provide them with a better technique or approach to overcoming the problems they are having.
