In the second simulation, the LEM is again moving downward towardthe landing pad. You need to set the forces of both engines toachieve a net acceleration directly upward of 4.12 m/s2. The massof the module is 8910 kg, and it does not change significantly asthe engines burn fuel. As an astronaut, you know that the rate ofacceleration due to the Moon's gravity is 1.62 m/s2.
To solve this problem, first calculate the total vertical forcethat should be provided by the engines to counter the Moon'sgravity and provide a net upward acceleration of 4.12 m/s2. Thiswill give you one equation involving the two unknown engine forces.The horizontal components of the misaligned engine forces muststill balance so that the LEM stays on course. This gives youanother equation. Solve the two equations and enter the forcevalues to the nearest 100 N.
